Question: If somebody who has died wants to help someone who is still alive, can they take the form of an angel and watch over that person?Sri Chinmoy: Those souls have their own divinity. They do not need an angel's help to come and visit their dear ones. Angels are always hovering over this earth-planet. They should be invoked by the sincere seekers.
