Question: Do you believe in ghosts?Sri Chinmoy: Certainly. Many, many times I have seen ghosts. They are dissatisfied and destructive vital beings. When undivine people die, because their lower desires have not been fulfilled, their vital beings are very dissatisfied. Ghosts have the capacity to create tremendous fear in people whom they have attacked. For months and even years after the attack has taken place, the victim may suffer from fear. Ghosts are very frightening and treacherous.
