Purity is the power to see the beautiful in all things and in all functions of life, and to glorify all actions by the spirit of unselfishness.
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.
