Question: Is it okay to let a dying person hold the hand of someone when they are in the final stage of dying?
Answer: The dying gripping the living is okay; but not the other way round, as it easily stirs attachment or aversion, while causing pain due to magnified sensitivity when dying. However, if the dying grips the living very tightly, it is already sign of strong attachment. There should be urging of letting go in good time.
