The early Buddhist sutras–scriptures attributed to the Buddha–speak of how attachment or craving constitute a primary source of our suffering, and how true freedom from suffering emerges through letting go of attachment or craving. Underlying these statements is an important psychological insight that draws an intimate connection between our perceptions of the world and the experience they give rise to on the one hand, and the arising of craving and how this leads us to act in a particular way on the other.

Brain mechanisms for intensely “wanting” something are different from the mechanisms for “liking” that same thing. “Wanting” generators, robust and large mechanisms that include many brain structures, are easily stimulated into highly reactive states. In stimulated brain states, encountering cues related to the temptation (or vividly imagining it) triggers intense pulses of craving. In addicts, the brain “wanting” generators may become further stimulated through neural sensitization by drugs (or by natural causes).

Lewis begins by describing a typical episode of pursuing and taking drugs based on his own experience of addiction during his 20s. This vignette demonstrates how thoughts about drugs and feelings of craving grow together in a person’s mind, until he or she finally gives in. Then comes the loss and despair, and the cycle repeats itself. According to psychological theory, the attraction to the cycle of craving and the use of drugs increases over months and years.

For many years, physicist Arthur Zajonc and neuroscientist Richard Davidson have worked with the Dalai Lama at the intersection of contemporary science and Buddhist thought. They offered their views on the power of this dialogue, and its significance for themselves and their work. This has led to larger questions of wider importance. Why are Western scientists interested in a dialogue with Buddhism or the contemplative traditions more generally?

Distinctions between pain and suffering are critical and relevant within the context of Buddhist thought and practice. This talk will map out a Buddhist perspective on suffering, its ultimate causes, the possibility of liberation from suffering, and a systematic path for its realization. It will touch on what Buddhists refer to as universal qual­ities of the human mind that are directly accessible through the cul­tivation of awareness through meditation.
