I dreamed that my grandfather who died had a headache!

Because your grandfather was greedy for money before his death, he fell on the road of hungry ghosts after his death. Besides, there are still outstanding debts in the past, so I am still suffering. I want you to help him because of the pain and because I have a deep fate with you. If you are really filial, I suggest you don't eat leeks. Read the Tibetan scriptures to him once a day, three or five times or seven times, and return the merits of chanting to him. He is likely to get pleasure from pain.
