the eye of enlightenment

For thousands of years oriental mystics have credited man with a third eye ,called the eye of enlightenment which is said to grant man with divine knowledge.

Now western scientists have begun to embrace the concept of this 'third eye'.The third eye not literally an eye is actually a gland called the pineal gland.This gland located at the back of the skull almost exactly on the midline of the brain.This is on of the most primitive parts of the brain and like the eye,the gland is sensitive to changes in light intensity.It has been found that in frogs the gland acts like a wavelength discriminator and converts light of certain wavelengths into nerve impulses!In humans it has been found that the pineal gland is the reservoir of the chemical substance called serotonin for the whole brain.
in 1954 scientists made a staggering discovery ;the chemical seems to be the key to rational thought,when serotonin is present in the brain man can 'think straight'.But it's absence causes hallucinations to occur similar to those seen in patients suffering from schizophrenia.
It seems that the addicting drug LSD(lysergic acid) which is an hallucinogen has a serious negative impact on serotonin.The LSD molecules go to the brain and block out the sites where serotonin acts.Thus the hallucinogenic nature of LSD is because it causes severe serotonin deficiency.Serotonin is found to be a common chemical in nature,found in the saliva of octopus ,bananas and plums.Remarkably the species of the fig tree under which Buddha attained enlightenment also contained staggering amounts of the chemical!!So quite literally the pineal gland is the one and truly eye of enlightenment.
