Once, I had a friend whose mother died of cancer at the age of 46. Within three months of his death, he was a little overwhelmed. He felt that the world was too cruel. His mother said to go, and he would often dream of his mother, which led to a little trance. He always felt that his mother was beside him. At that time, they often asked me, where will people go after they die? If we encounter the death of relatives and friends, how should we get out of the pain?
