It is possible that the cause of depression can be linked to a trapping of foreign human Spirits within a living human beings body. In her book, Remarkable Healings, Shakuntala Modi, M.D., a board certified Psychiatrist, sheds light on her remarkable discovery that there is truth to this claim. Modi believes that a person can be healed from depression and physical ailments by helping spirits which have become trapped within her patient's body, to exit the body, and find their way to a spiritual afterlife.
