I hope this has helped some of you, it sounds like it has
My experience is this: When I envision the skeleton I am, and it's disintegration into the earth- it reminds me that I am so small, my life is so small- in the great realm of the earth and cosmos. It is comforting to know that all my pain, what I feel- will be reduced to a pile of dirt- just like everyone else. No one escapes this, and all the noise between birth and death ultimately amounts to nothing. And that reminds me to be as happy as possible at every given moment. I, like many- struggle with sadness and loneliness. This exercise has been helpful.
