How to avoid family drowning? My uncle drowned fishing for fish food in the morning. How can I mourn in different places?

You give him merit in a Buddhist temple, or recite scriptures and Buddha to him, and his merit will be returned to him. He may catch fish and worms and kill too many animals. Thousands of lives. If you do merit for him, according to the Tibetan scriptures, he can only get one seventh, and the rest is yours. Let him suffer less. Unless you give him a big heart to practice.
