Agnihotra

H.H.Sri Swami Sivananda: Yes. All spirits do not possess the power of materialization. Only advanced spirits that are endowed with psychic power are able to materialize. They take human form, sit in the chair in the seance and shake hands with those who sit in the seance. They talk also. The touch is as tangible and warm as that of a living human body. In a short time, the hand of the spirit melts away. Photographs of the spirits also have been taken.
