I just read this paragraph written by Pema Chodron and I thought it was beautiful
“With each meditation session, you could train in opening to whatever arises, and relaxing with the immediacy of your experience. Just acknowledge your pleasant and unpleasant thoughts without bias and let them pass away. Then at the time of death, you will be ready to let go of your attachment to this life and surrender to the process of dissolving.”
It seems to me she has just described how to live a purposeful life.
It is taken from her book “No time to Lose” in the chapter on enthusiasm. There are reviews of the book and where to buy it here
