pineal gland is stated by author of the book Yoga, Higher and Lower as "the chief
organ of spiritualism in human brain, the seat of genius, the magical sesameuttered
by the purified will of mystic, which opens all avenues of truth for him who knows how to
use it" (C B V Rajam, Aiyar: Rambles in the Vedanta).
These are the two glands where the minds operate
and, in the case of the "seizure" by devils, the mind of the devil or the ghost
for the time being displaces the mind of the victim and functions on the site of these
important nerve centres.
