Overview of Rebirth and the Twelve Links

Introduction

The topic for this series is the practical application of the twelve links of dependent arising. These twelve links are basically an explanation for how samsara works. Samsara means uncontrollably recurring rebirth and not just the uncontrollable recurring problems in our own lifetimes. More specifically, it explains how rebirth works. For most of us coming from non-traditional Asian society, we don’t have as part of our culture a belief in rebirth. Maybe we believe in an afterlife, but not a continuing cycle of rebirth, recurring out of our control, over and over filled suffering and problems inherent in having a body and mind generated through the influence of confusion, and of unawareness. All of the problems follow from that unawareness or ignorance of how we exist and so on. We can use our understanding of the twelve links to gain a bit more understanding of how rebirth works and maybe gain some actual confidence about it. 

Traditionally, the dividing line presented for a Buddhist practice is that it is intended for benefiting future lives. If the purpose is just to benefit this life, it’s considered a worldly or mundane type of practice. The different levels of motivation as presented in the Lam-rim, The Graded Stages of the Path, introduced in Tibet by Atisha, all have to do with rebirth. We’re initially motivated to try to improve our future lives; next to gain liberation completely from any further samsaric rebirth; and finally to gain the enlightened state of a Buddha so we can help everyone else overcome rebirth. 

When we practice tantra, specifically the highest class of tantra, we are strongly aiming to stop this process of rebirth by mimicking the process of death, the in between state or bardo, and how we are reborn. We want to transform that process so that instead of our ordinary death, bardo, and rebirth, our mind passes more and more toward the subtle clear-light state, and then we arise with the various Buddha bodies instead. Undoubtedly, this entire path and presentation in Buddhism all revolves around rebirth. 

For most of us, because it is not a part of our culture to understand and believe in rebirth, it’s a bit difficult to really be sincere in our practice of the Dharma. We tend to need to practice on the basis of faith. We give the whole concept of rebirth the benefit of the doubt and we assume that it is true. We withhold a small degree of judgment on it and proceed. But Buddha advised us not to believe anything that was said just out of faith in him; but, to examine it ourselves, test it as if buying gold. Only then should we accept the words of the Buddha and the great masters who followed.

Ways of Examining Rebirth

There are many different ways to examine rebirth. The most profound way is to understand continuities. This means that things arise dependently on causes and condition. If that is the case, we can think in terms of the mind or consciousness; however that too can become a bit problematic because many Western scientists don’t accept the mind or consciousness as being something different from just a physical property of the brain, chemicals, electrical impulses, hormones and so on. Nevertheless, if we think of mind or consciousness in terms of the subjective individual experiencing of things, then if it’s continuity from moment to moment, there must be causes and conditions driving it. Consequently, we would have to examine if there is an absolute beginning and end to this stream of continuity. Only by analyzing in that way can we conclude that there is no beginning and no end. Dealing with the concept of infinity is not so easy for most of us. The logic is something that requires getting used to. As mentioned, this approach is the most profound or deepest way to become convinced of rebirth.

An easier way of approaching it is to understand how it works and that is what the twelve links of dependent arising explain. With this information we can examine how it arises and whether it is something helpful that we can work with or just some impractical theoretical explanation. After all, everything that Buddha taught was intended to help us to overcome difficulties and suffering. We always need to look at any Buddhist teachings in terms of how it can help us overcome suffering and not creating more suffering and problems. 

Sentient Beings

In our discussion of rebirth, we are talking about sentient beings. If we look at the term, the actual meaning is someone with a limited mind and body. This isn’t in the sense of being handicapped, but more like a magnet, we attract problems, sickness, and old age. As Shantideva describes, we become like a slave taking care of the body. We have to feed it, wash it, clothe it, and give it rest. We are constantly serving our bodies. It is an unending task. If we are human, with rebirth, we have to relearn everything that was learned previously including how to walk, talk, let alone go to school again. 

In the Mahayana practices of the four close placements of mindfulness, when focused on the body, we aren’t focusing on the sensations of the body as in the Theravada method. Instead, we focus on the body from the perspective of the first noble truth, that this body is really problematic. As a sentient being we have a limited body and mind. We can only see out of these two holes in the front of our faces, and we aren’t able to understand so many things. As we age, our memory and mindfulness decrease, and all our senses weaken. There are so many limitations. A Buddha is not a sentient being; a Buddha has unlimited body and mind. 

The twelve links explain how this constantly occurs, how we repeatedly have this type of body and mind. It is generated from our unawareness of ignorance, contains more of this unawareness and ignorance and perpetuates itself in this way. The twelve links provide a profound and sophisticated explanation of how uncontrollably recurring rebirth works and how we can stop it. We can deal with this on the actual Dharma level of wanting to stop rebirth, but it can also help us in our daily life even without the confidence that there is such a thing as rebirth. 

In this series of talks, we won’t be discussing in great depth the details about the twelve links. There are many comprehensive articles about this on the website for example. Instead, we will have a shorter presentation of these details and thereafter examine more deeply how we can actually work with this material on a practical level in our daily lives.

The Development of the Five Aggregates

Consciousness

To list them, but not in the usual order, we have some type of consciousness. The Buddhist description is that we have individual types of consciousness such as visual, audio, olfactory, taste, physical sensations. 

Forms of Physical Phenomena

Next, there is some sort of object of these consciousnesses; not so much the external object, but what we experience. For example, we experience a sight, a sound, a smell, a taste, or physical sensations throughout the body. In every moment, there is some sort of object like that. This aggregate also includes the sensors, such as the photo sensitive cells of the eyes, the sound sensitive cells of the ears and so on.

Distinguishing

Sometimes this aggregate is referred to as recognition, but that is too advanced. Within a sense field in which we are perceiving pixels, or on a larger scale perceiving colored shapes, how are we able to put certain groups of pixels or colored shapes into objects? It’s quite amazing. We do this with distinguishing in that we are able to distinguish one object from another object within that sense field. We can distinguish one person’s face from the door behind the person. We don’t just put it all into one object. This is going on all the time, otherwise it’s impossible to deal with life and perception. 

Feeling a Level of Happiness or Unhappiness

We experience things with some level of happiness or unhappiness. This is the next aggregate. It doesn’t have to be dramatic. We will speak more about that later.

Other Affecting Variables

This is the aggregate of everything else, all the emotions, and almost mechanical things, the mental factors involved with cognition, such as attention, concentration, intention, and mindfulness.

In every moment there are at least one or more of these aggregates going on. We can see and hear at the same time and also feel the sensation of the temperature of the room. We might not pay much attention to all the information coming in from all our senses simultaneously; however, there’s always some attention, some emotions, and some level of how we experience all of this: happy, unhappy, don’t care. Something is always going on. 

Therefore, when we speak of the resultant links of what has been thrown, this is not merely explaining the arising and development of the fetus until we are actually born. It also explains how the aggregates emerge. Thereby, we get the full scope of these five aggregates. 

Second Part of Loaded Consciousness

We begin with loaded consciousness, actually the second half of loaded consciousness. There is nothing symmetrical about this system, so give up that attachment to symmetry as we study this, because the first grouping has two and a half links and the second grouping has four and a half. 

The second part of loaded consciousness is at the time of the resultant links of what has been thrown. This is the moment of conception, and at that moment basically it just lasts an instance. There is the consciousness, and it makes the connection with some physical substance, a sperm and an egg. We won’t get into the discussion of when this occurs because even scientists have difficulty specifying that. The focus is on the consciousness going into another rebirth.

Nameable Mental Faculties with or without Gross Form

“With or without gross form” means that it includes the formless realms where we have the subtlest type of form. In this fourth link things can be given a name; they are nameable. What we have is undifferentiated aggregates of consciousness and form. The other aggregates are in a potential. As the fetus first starts to develop, we just have consciousness. It’s not differentiated yet into seeing, hearing, smelling, or mental consciousness. The same thing is in terms of the form aggregate in that there is only the body basically. It’s analogous to speaking of the fertilized egg as having the potentials, or scientifically, the DNA to develop into a human or to develop into a fly. If we use that analogy, we can understand that everything that may develop further is only in a potential form at this level. In a sense, it is already set in that if it’s going to be a fly, it won’t be a human rebirth. That is what is involved in this fourth link.

Stimulators of Consciousness

As the fetus develops, we get the fifth link, the stimulators of consciousness. These are the physical things that will stimulate the consciousnesses. This is referring to the stage at which we move from undifferentiated into the specific different types of consciousness. The body, the form, has developed to the point in which we have the so-called cognitive sensors. We have some cells that are photo-sensitive, others to perceive sound, smell, taste, and physical sensation and thought in general. At this stage the stimulators are on the side of the form aggregate. The sensory cells are becoming specified to different senses and therefore there are different types of objects of the senses. The fetus is able to perceive, in a sense, even if it is darkness or some sense of sound. 

What this implies is that the aggregate of distinguishing begins to manifest and can begin to distinguish an object as a sound, a sight, a sensation, and so on.

Contacting Awareness

Then we have the sixth link, contacting awareness. It’s a mental factor; this isn’t referring to the physical contact with an object. Contacting awareness is the experiencing of an object as being pleasant, unpleasant, or neutral. It refers to how the consciousness is having contact with an object. In the link before, there were different objects and some degree of distinguishing the type of sensory object. Now, in this link, the fetus begins to interact with objects in a sense of experiencing it as pleasant, unpleasant, or neutral. This is already some type of ripening of karma. 

Obviously, once we are born, we experience things as pleasant, unpleasant and so on. One person finds a taste pleasant and another doesn’t. It’s clear that this is individual and thereby coming from karma. The contacting awareness is in the aggregate of other affecting variables, and these are starting to become more manifest.

Feeling Some Level of Happiness

In the seventh link, there is some feeling of happiness, unhappiness or a neutral feeling. Neutral refers to a state in the formless realms and what we might experience in very deep meditation, deeper than happy and unhappy. In response to pleasant contacting awareness, a pleasant sound, for example, when the mother plays nice music for the fetus. The fetus experiences that as pleasant. The mother might eat something very soothing, and this is a pleasant sensation. In this way the fetus has some experience with happiness and wanting it to continue. The mother might eat something with a lot of chili in it, and it’s an unpleasant sensation for the fetus and it experiences it with unhappiness and would like it to stop and go away. 

The aggregate of feeling has become manifest and now we have all five aggregates. These are the resultant links of what has been thrown, and they describe the development of the fetus and the emergence of the full scheme of the five aggregates from the potential just with the consciousness and then coming in contact with a sperm and egg in reference to being born from a womb. 

To review, we have: 

  • The second half of loaded consciousness at the time of the resultant links of what has been thrown
  • Nameable mental faculties with or without gross form
  • Stimulators of consciousness
  • Contacting awareness
  • Feeling a level of happiness.

We can memorize these, of course, but more importantly try to relate it to the progression that is occurring. We have undifferentiated consciousness, and then the one fertilized cell and it develops into different types of cells that can perceive sensory objects and then begin to be able to distinguish things. Then, we can find these things pleasant or unpleasant with contacting awareness and then have the feeling of happiness or unhappiness based on that. This is the progression of the fetus.

If we look at another explanation of these twelve links, we can find this process happening all the time when we are alive as well. It’s a very helpful description of how our experience develops. Let’s digest that for a moment.

Basically, to put it very simply, we have confusion, unawareness, and we act compulsively based on that and disturbing emotions. This builds up potentials on the consciousness. We die and in the next rebirth, all these potentials go through a gradual process of becoming manifest. Included in that will be more ignorance, unawareness and compulsive behavior thrown by this unawareness and compulsive karma, it’s going to be very limited and problematic. It’s going to get sick, get old, and be confused. As a fly, we certainly won’t understand very much.

Level of Happiness/Unhappiness and Feelings as the Cause of Suffering

These are the causal links that activate. This is what we will explore more deeply as these are very crucial. We do these things all the time and not just at the moment of death. But when the twelve links are describing the process of rebirth, it’s very specific to the moment of death. It all is aimed at feeling a level of happiness or unhappiness. Therefore, when we practice the four close placements of mindfulness in the Mahayana, as mentioned, we focus on the body as suffering, an example of first noble truth. We focus on the feelings, as the second noble truth. The feelings are the cause of our suffering. This is another example of giving the name of the result to the cause. Our disturbing attitudes and emotions towards our feeling are the cause of all the problems and suffering. How we deal with feelings of happiness and unhappiness is problematic and this is communicated in the system of these twelve links.

Our problems are caused by how we deal with happiness or unhappiness, and how we deal with the objects we are happy or unhappy about and then, “me” who is experiencing this. If we deal with it in a confused way, we are going to generate more samsaric further existence and rebirth. 

Review and Overview

These are the twelve links of dependent arising, in brief. To review, we have the causal links that throw, including unawareness, affecting impulses, and loaded consciousness at the time that makes it thrown. This is going on all the time, and we are building up more and more karmic potentials because of compulsive behavior based on unawareness of how we and everyone else exists. It’s all about the attitude of “me, me, me” and “poor me.” Then depressing thoughts and so on follow. 

The causal links that activate are what will activate the potentials to cause more rebirths. They are focused on the second group, the resultant links of what has been thrown including the whole development in each lifetime of the fetus so that we actually have these experiences of happiness or unhappiness. That is what will activate our attitudes toward them, and those attitudes will activate more karmic potentials and then we have the resultant links of what is actualized. This includes conception, again and dying.

It works like that. When we think in terms of rebirth, this can be completed in two or three lifetimes. In two lifetimes, we build up these karmic potentials and we activate them in one lifetime in that the first and third sets occur in one lifetime, while the second and fourth sets occur in the next lifetime. We have the development of the fetus and conception, aging and dying in the second lifetime. It can also occur in three lifetimes, and of course there can be many lifetimes in between. In one lifetime, we build up a potential for a particular type of rebirth, and in another lifetime, we activate them, and in the third lifetime, we get the resultant life. In this way, there can be two or three lifetimes. This is the way it functions in terms of rebirth. 

Think about that for a little while.

When we think about it, of course, we could get a bit unsettled if we try to list and remember the twelve. Don’t get caught up in that as a first step. It takes a while to become fluent with this system. That’s okay; it is complex. To begin, the significant point is just to think in terms of our confusion about how we exist, and how thereby, we have disturbing emotions, act destructively, and build up potentials. We activate these potentials with more confusion and then we have rebirth. We continue with all this, and the sources of all the confusion. It just continues like that. This is the essence of the twelve links. 

This goes back to the discussion of becoming convinced of rebirth in that we can become convinced on a theoretical level of cause and effect. It makes no sense to have an absolute beginning and an absolute end. On a more conventional level, we can approach it by understanding how this perpetuates. We can begin to understand the causal process of making the consciousness go on and on, especially in terms of the continuity of suffering and problems. If we start to recognize that process in our daily lives, we can discover how we’re building up more and more potential because we act so compulsively. We are always thinking of “me, me, me,” and “you, you, you.” “You did this when I want that.” In fact, we really don’t handle our moods of happy and unhappy very well at all and that just perpetuates the ups and downs of our daily lives with all its problems.

Rebirth

If we begin to recognize this, it helps us realize how this whole process is self-perpetuating. When we understand how cause and effect operate with all these factors, then it becomes easier to deal with the viewpoint of no beginning and no end. Logically, this is because, if it’s being perpetuated moment to moment to moment by all the confusion, how could it start from nothing and then all of a sudden a nothing becomes a something? Alternatively, how could it be that something completely external randomly starts it all as if by pressing a button. That doesn’t make any sense. 

In this way we can start to become more comfortable with the idea of rebirth. However, all but one the non-Buddhist Indian schools also accept rebirth. However, we need to understand how the self exists that is taking rebirth and what is it that is continuing. When we misunderstand that or don’t know, that’s the first link, unawareness. In order to really understand rebirth, it’s not enough to just understand these links in terms of how it’s perpetuated. It is essential that we get rid of our unawareness of how we exist. Who is it, what is it that is being reborn? We’re not talking about some static, unchanging “me” that can be known all by itself as if “I want you to love me for ‘me.’”

The twelve links system is a start, and it indicates the importance of that understanding of how we exist and how everybody exists.

Questions and Answers

The formulation is that the karmic potentials are activated in future lives, but would it also be that they can be activated in the current lifetime?

The karmic potentials are activated at the time of death in this lifetime according to the explanation of rebirth. Let’s say, in this lifetime, we build up the karmic potential to be reborn as a human with various characteristics. But at the time of death, for example, we activate karmic potentials to be reborn as a fly. In the next lifetime, we are a fly, and at the end of that lifetime, we could activate a potential to be born as a human. It’s very unlikely as a fly, however. 

Aren’t we also always building up karma that has an influence on the present life? Would we use a different terminology for that?

This is exactly the point of what we discuss in the rest of this series. We can apply this entire analysis to our daily life and not just the time of death in regard to how we deal with our feelings. This is the practical application of these twelve links. The standard explanation is in terms of activating these things at the time of death. But also there is an alternative explanation in Theravada about how all the twelve links can occur at the same time all the time. In the rest of the seminar, through analysis we can examine and work with that to see how this would function. 

The fact that the traditional explanation is talking about the time of death underlies how important it is to die with peace of mind and not completely unsettled and upset about pain or not wanting to leave our loved ones and these sorts of things. That’s why in the highest class of tantra, we rehearse process of death and what is actually going to happen as we die. In this way, we can approach it calmly.

Let me share with you His Holiness the Dalai Lama’s advice about dying. In the higher tantra practices, there are all sorts of elaborate visualizations and things that one can familiarize oneself with that will occur in the process of dying. His Holiness has said that this is all very nice and helpful to know what is going to happen, but for the vast majority of us it is too difficult to actually try to do that when we are dying. This is especially if we are trying to visualize ourselves as some deity, and then become confused about what is being held in this or that arm and people freak out about not doing it right. His Holiness advises that unless we are super advanced, it is far more beneficial to die with thoughts of bodhichitta: “May I continue to have a precious human rebirth so that I can continue to work toward enlightenment to benefit all beings.” That’s the best thought for the vast majority of us to die with and become familiar with beforehand. It’s not going to be confusing.

This is very helpful advice because often we imagine that we are very advanced practitioners when in fact, in crucial moments like at death, we haven’t built up a strong enough habit to sustain these very complicated practices. If we accept the reality of that, we will be better able to deal with death. As the twelve links indicate, our attitude at the time of death is crucial in terms of what karmic cluster of potentials we are going to activate.

There is throwing karma and completing karma. Throwing karma is going to affect what life form we will have, whether human, dog, fly, ghost or whatever. Completing karma includes the circumstances of that such as level of intelligence, anger, etc. All of these mental factors have their own tendencies and potentials. Also, it includes the circumstances and environmental condition. Are we going to be a street dog in Calcutta or the pet of the Dalai Lama? Clearly, what is very important is the state of mind in which we die, even if we can’t focus on something like the voidness of the clear light mind. We need to take this seriously, and at least have the initial level of motivation for another precious human rebirth to continue on the path.

Dedication

We think whatever understanding, whatever positive force has come from this, may it go deeper and deeper, and act as a cause for all beings to reach the enlightened state of a Buddha for the benefit of us all.
