Naturally, most of us would like to die a peaceful death, but it is clear that we cannot hope to die peacefully if our lives have been full of violence, or if our minds have mostly been agitated by emotions like anger, attachment, or fear. So if we wish to die well, we must learn how to live well: Hoping for a peaceful death, we must cultivate peace in our mind, and in our way of life.
Serious spiritual practice is more than serene walks in the woods, lit candles and incense. You have to be committed. Your have to be willing to enter into your own darkness and transcend it.
