Exploring the Mysteries

of the Pineal Gland

Background

The pineal gland, often referred to
as the “third eye,” has always been a

subject of fascination and mystery.
Hindu philosophy and Vedic medicine,
written some 5000 years ago, describe

the pineal – “the sixth chakra”, according
to these traditions – as a window to the

spiritual world, where mental power
of the pineal gland resides, associating
this gland with clairvoyance and

meditation, professing that its activity is
nocturnal. The first detailed descriptions

of the pineal are found in the works of
Galen (131-200 AD), expounding on
a theory that proposed the gland was

an organ exercising valvular control.
His underlying theoretical bases were

founded on the pneumatic school of
Alexandria. Acting like a pump, the
pineal gland was thought to distribute

“spiritus animalis” around the body.
Galen’s whole structure was called the

“pneumatic-ventricular model” and
was purely hydraulic in nature. The
“pneumatic-ventricular model” provided

the theoretical basis of René Descartes
