“Every education minister today has a chance of introducing in his education today some simple technique, some simple natural insights into the total reality of life, which the physical sciences have explored in terms of “Unified Field”, which the ancient Vedic wisdom has located in the Self referral consciousness of everyone.”

First Words
Cosmic Consciousness (1901)
Context: Cosmic Consciousness … is a higher form of consciousness than that possessed by the ordinary man. This last is called Self Consciousness and is that faculty upon which rests all of our life (both subjective and objective) which is not common to us and the higher animals, except that small part of it which is derived from the few individuals who have had the higher consciousness above named. To make the matter clear it must be understood that there are three forms or grades of consciousness. (1) Simple Consciousness, which is possessed by say the upper half of the animal kingdom. By means of this faculty a dog or a horse is just as conscious of the things about him as a man is; he is also conscious of his own limbs and body and he knows that these are a part of himself. (2) Over and above this Simple Consciousness, which is possessed by man as by animals, man has another which is called Self Consciousness. By virtue of this faculty man is not only conscious of trees, rocks, waters, his own limbs and body, but he becomes conscious of himself as a distinct entity apart from all the rest of the universe. It is as good as certain that no animal can realize himself in that way. … The animal is, as it were, immersed in his consciousness as a fish in the sea, he cannot, even in imagination, get outside of it for one moment so as to realize it. … Cosmic Consciousness is a third form which is as far above Self Consciousness as is that above Simple Consciousness. With this form, of course, both simple and self consciousness persist (as simple consciousness persists when self consciousness is acquired), but added to them is the new faculty … The prime characteristic of cosmic consciousness is, as its name implies, a consciousness of the cosmos, that is, of the life and order of the universe … Along with the consciousness of the cosmos there occurs an intellectual enlightenment or illumination which alone would place the individual on a new plane of existence — would make him almost a member of a new species. To this is added a state of moral exaltation, an indescribable feeling of elevation, elation and joyousness, and a quickening of the moral sense, which is fully as striking and more important both to the individual and to the race than is the enhanced intellectual power. With these come, what may be called, a sense of immortality, a consciousness of eternal life, not a conviction that he shall have this, but the consciousness that he has it already.

Notes from Underground (1864)
Context: Every man has some reminiscences which he would not tell to everyone, but only to his friends. He has others which he would not reveal even to his friends, but only to himself, and that in secret. But finally there are still others which a man is even afraid to tell himself, and every decent man has a considerable number of such things stored away. That is, one can even say that the more decent he is, the greater the number of such things in his mind.
