The purpose of yoga, Gopi Krishna

"What has to be borne in mind, first, is that the paranormal gifts of a medium or a clairvoyant are a form of genius about which, to this day, the scholars have not been able to form a clear opinion. The general idea in the minds of the investigators of the phenomena is that a new force or a new energy is involved, or that some disembodied spirits or elements work through the minds of certain specially constituted persons to produce the weird and bizarre displays in violation of natural laws. This is not the case. The actual position is that all these phenomena occur due to the working of a still developing compartment in the human brain which I call “the paranormal chamber”. This still forming supersensory organ or the Third Eye is slowly building up in the cranium as a result of evolutionary processes still active in the human frame. This fact has been known from very ancient times. In fact, the practices of Yoga and all other religious or occult disciplines are designed to activate this centre to gain knowledge of other intelligent forces operating in this universe. Illumination or enlightenment, which has been a regular feature of history, occurs when the centre is fully opened with the upward flow of a new form of life-energy through the spinal canal into the brain.
All the new knowledge gained by mankind, all the great discoveries of science, all mediumistic and psychical phenomena, all miraculous and supernormal events, associated with prophets, seers, oracles, geniuses, mediums and sensitives, owe their origin to this paranormal receptor, still in a state of growth, which will become fully developed and operative in the man to come. The evidence pointing to this extraordinary performance of the human brain is overwhelming. Only it has not been systematically arranged and presented so far. Apart from the so-called psychical phenomena we have other striking examples unmistakably pointing in the same direction. A few of these will be discussed in this work. They refer to prodigious feats of astronomical calculation, monumental construction, or surpassing literary achievements of ancient times, all of which pose a riddle which has not been answered to this day."
