I want to share two notes. The first I found after watching the final season of The Good Place. This isn't a quote from the show, but a quote from The Heart of the Buddha's Teaching that the show references:
"When we look at the ocean, we see that each wave has a beginning and an end. A wave can be compared with other waves, and we can call it more or less beautiful, higher or lower, longer lasting or less long lasting. But if we look more deeply, we see that a wave is made of water. While living the life of a wave, it also lives the life of water. It would be sad if the wave did not know that it is water. It would think, Some day, I will have to die. This period of time is my life span, and when I arrive at the shore, I will return to nonbeing. These notions will cause the wave fear and anguish. We have to help it remove the notions of self, person, living being, and life span if we want the wave to be free and happy."
The second is from a Redditor responding to the death of someone's friend I am only sharing a bit, but I encourage you to read it fully:
"As for grief, you'll find it comes in waves. When the ship is first wrecked, you're drowning, with wreckage all around you. Everything floating around you reminds you of the beauty and the magnificence of the ship that was, and is no more. And all you can do is float. You find some piece of the wreckage and you hang on for a while. Maybe it's some physical thing. Maybe it's a happy memory or a photograph. Maybe it's a person who is also floating. For a while, all you can do is float. Stay alive."
