Astral Projection: Physical Body
built 208 days ago
ASTRAL PROJECTION- This is where the Consciousness & the Astral body separate together from the physical body. The practitioner has use of all fives senses plus those used by the Astral body. You may have a sense of flying or floating. Vivid dreams are often natural AP during sleep. It's perfectly safe. Nothing can enter the physical body while on an Astral projection as only you have the exact key. At any sign of danger the Astral body is "reeled in" rather quickly.

ETHERIC PROJECTION - This is where the Consciousness, the Astral body & the etheric body separate together from the physical body. The ectoplasm of the Etheric body can been seen other. The physical body is reduced to a state of near catalepsy during the projection and must be protected from sudden shock or disturbance as there is a rare occurrence of physical death.
