The Dalai Lama once said that all of our problems stem from mistaken perception. That is why there is so much emphasis on true knowledge.
This talk explores the quality factor of perception, and how when it is colored by unwholesome states of mind we cannot accurately recognize reality, and so respond in ways that only increase our confusion.
The contemplation of what makes our life precious brings commitment and a sense of urgency to our practice. It is learning to remember what is of enduring value in this fleeting, fragile life.
