Drugs and certain yogic techniques can force the pineal open prematurely before the mind is ready for psychic powers, and this can lead to psychosis. Sungazing, if done correctly, gradually awakens the pineal, along with the pituitary so that the person is not shocked by experiences of higher consciousness, and these experiences are not colored by negative images in the mind.
The use of mantras and chanting can also gradually awaken the pineal because it sits above the mouth suspended in the third ventricle, a chamber filled with cerebrospinal fluid, what some esotericists have called “the grail.” Its location above the mouth in a fluid chamber makes the pineal gland quite uniquely positioned to respond to sonic vibrations.
Manly P. Hall, in The Opening of the Third Eye stated that the pineal gland “vibrating at a very high rate of speed, is the actual cause of true spiritual illumination.” The pineal governs energy level. Thus, the more it is stimulated, the higher a person’s energy level.
