Seeing beginnings and endings — the arising and passing away of all conditioned forms — is a vital step in developing the understanding that nothing exists apart from interdependent, cause-and-effect relationships. To see the beginnings and endings is also, in my experience, a great support in difficult times. Early on, as I began to trust in the fiber of my being that nothing lasts, I became less afraid of pain. The fact that everything has an end comforted me. “One way or another,” I would say to myself, “this too will pass.” I was glad I saw that. I didn’t think much, in those initial moments of insight, about how the pleasant things change as well as the difficult ones. I know that when I struggle with the pain of any loss, the struggle preoccupies my mind and leaves no room for hope. When I recognize the pain I feel as the legitimate result of loss, I am respectful of its presence and kind to myself. My mind always relaxes when it is kind, and around the edges of the truth of whatever has ended, I see displays of what might be beginning.
