As dharma students our task is to know reality. And, as the Buddha tells us, there is a conditioned reality, the reality of the senses; and there's an unconditioned reality, a reality that is timeless. The path leads us to knowing this reality: ultimate reality. In this talk, Peter Doobinin discusses ultimate reality, what it is, and what we need to do to know it. The talk was given in the winter of 2025.
