Following feeling, relying on liking or wanting, we are not free. The freedom to do as we like is not freedom of choice because we are ruled by the powerful property of feeling; we cannot choose apart from liking and disliking. Likes and dislikes may be articulated in the form of sophisticated-sounding opinions, but the decision is made for us by feeling. The Western world places a high value on personal feelings and opinions: Each individual has a right to an opinion. But rarely do we question how we have arrived at our opinion. Upon examination, we may discover that opinions tend to stem from convenience, familiarity, and selfishness–what feels good or what is pleasing or comfortable to us. Upon this basis, we act, and receive the consequences of our action. Even if we compile a large number of such opinions, there is no guarantee that we will develop a wise perspective as a ground for action. Often this process only creates a mass of confusion, for opinions of one individual tend to conflict with the opinions of another. If there appears to be agreement, we tend to assume this agreement will remain stable. But agreement only means that the needs of the individuals involved are temporarily similar, and when those needs shift, agreement will evaporate. To make certain decisions, we rely on logic or scientific findings, which are supposedly free from personal opinion but are still weighted with the opinions of a particular culture. This style of knowing is founded on particular distinctions and ignores other possibilities. The evidence is clear that the scope of modern scientific knowledge is limited, for this knowledge is not yet able to predict and control the side-effects resulting from its own use. Its solutions in turn create more problems, reinforcing the circular patterns of samsara. Only understanding that penetrates to the root causes of problems can break this circularity. Until we explore the depths of consciousness, we cannot resolve the fundamental questions that face human beings.

Actively, we are motivated by the never-ending desires of the self. We are compelled to pursue whatever the self imagines will satisfy its desires. We are convinced that satisfaction of desire is the source of true happiness. Yet the very nature of desire does not permit happiness. Like trying to quench one's thirst by drinking salt water, satisfying desire only stimulates the flow of desire. In the wake of fulfillment, desire once more stirs and reaches out. There is never lasting satisfaction, not even completion.

Both outer and inner phenomena arise as a result of causes and conditions. Outer phenomena, the things of the physical world, arise in a series of seven steps. The texts use the example of a seed giving rise to a plant that gives rise to a fruit. The seven steps are: seed, sprout, leaflets, stemmed plant, bud, flower, fruit. Each stage succeeds the previous one in time and in order, each giving rise to the next.

Through this process, wisdom clarifies the way that the mind manufacturers emotion and karma, and finally penetrates the illusion of self. Just as though one were investigating how a magician created his display of illusions, one studies mental events to understand the conditions and causes that support the operation of ordinary self-oriented experience. One first understands the root emotions as the basis for samsara, then studies the workings of the associated emotions and how each one manifests a distinctive character. Gradually, the manner in which the self supports emotion and emotion supports the sense of self becomes clear. Self and emotion are seen as relying on and reinforcing each other's existence. Understanding how this collusion gives rise to the whole range of samsaric delusion liberates the mind from all forms of deception.
