Is thinking about your death a "bad thought"?
Are people really trained to shut down reflections on the most basic facts of life as though there is something wrong or dangerous about contemplating simple reality?
Who is telling people that thinking about those things is bad, & how do you get people to stop chasing away every uncomfortable thought once they've learned the habit? Can we create a culture where it's normal to be aware of our own impermanence? Or is that too much to ask?
