The secretory activity of the pineal gland is only relatively understood. Historically, its location deep in the brain suggested to philosophers that it possessed particular importance. This combination led to its being a "mystery" gland with myth, superstition and occult theories surrounding its perceived functions.
René Descartes, who dedicated much time to the study of the pineal gland,called it the "seat of the soul."He believed that it was the point of connection between the intellect and the body. Descartes attached significance to the gland because he believed it to be the only section of the brain which existed as a single part, rather than one half of a pair. He argued that because a person can never have "more than one thought at a time", external stimuli must be united within the brain before being considered by the soul, and he considered the pineal gland to be situated in "the most suitable possible place for this purpose", located centrally in the brain and surrounded by branches of the carotid arteries.
Baruch de Spinoza criticized Descartes' viewpoint for neither following from self-evident premises nor being "clearly and distinctly perceived" (Descartes having previously asserted that he could not draw conclusions of this sort), and questioned what Descartes meant by talking of "the union of the mind and the body".
But all these theories about the pineal gland, as the third eye or center of the seventh chakra and others, based on assumptions. What about in reality? But in reality the soul does not connected with our body. The body has the ability to perceive the universal consciousness, just like an antenna captures the signal, so it's just a conductor. With the evolution of the brain signal becomes stronger and vice versa ... More information: see in my book...
The question then arises: who in this case acting as I am? The answer is simple, universal consciousness has the universal name - I am, but illusion comes from this: all the body organs are paired structure - lobed, including the pineal gland - a recent discovery, that leads to a duality - a source of names and forms
