Rohit Mehta, Founder of the Socialist party of India and Secretary of the International Theosophical Society, writes in his book, “The Science of Meditation” :
We have seen that the brain is working at present with a low potential of 10-12 percent. It must be supplied with a great amount of fresh energy. It is with this energy that the new centers of learning can be brought into existence in an unusual area of the brain. Without establishing such new reverberating centers in a revitalized brain, man cannot survive biologically or psychologically in this new phase of evolutionary growth.
