Richard Gombrich, a Buddhist scholar, called the Buddha a brilliant and original thinker on the level of Plato and Aristotle. But the Buddha wasn't interested in just speculative philosophy, but to understand why we suffer, and how to find freedom. The Four Noble Truths is his direct teaching on just that.
This third in a series of talks explores the formation of self through the chain of dependent origination, a detailed description of how we suffer. It then outlines approaches in meditation that let us step out of the chain of suffering and into a state of "unentangled knowing" in which we discover the possibility of freedom here and now.
