The Jivahood has gone now. The little ‘l’ has melted. The differentiating mind that splits up has vanished. All barriers, all sense of duality, differences, separateness have disappeared. There is no idea of time and space. There is only eternity. The ideas of caste, creed and colour have gone now. He has the feeling of Apta-Kama (one who has obtained all that he desires). He feels, “There is nothing more to be known by me.” He feels perfect awareness of superconscious plane of Knowledge and intuition. He knows the whole secret of Creation. He is Omniscient. He is a Sarva-Vit or Knower of all details of Creation. Absolute fearlessness, desirelessness, thoughtlessness, l-lessness, mine-lessness, angerlessness, Brahmic aura in the face, freedom from Harsha and Shoka are some of the signs that indicate that the man has reached the state of superconsciousness. He is also always in a state of perfect bliss. You can never see anger, depression, cheerlessness and sorrow in his face. You willfind elevation, joy and peace in his presence. Cosmic consciousness is perfect awareness of the oneness of life. The Yogi feels that the universe is filled with one life. He actually feels that there is no such thing as blind force or dead matter and that all is alive, vibrating and intelligent. This is the experience of scientist Bose also. He has demonstrated it through laboratory experiments. He who has cosmic consciousness feels that the universe is all his. He is one with the Supreme Lord. He is one with the Universal knowledge and Life. He experiences bliss and joy beyond understanding and description. ln the moment of illumination or great spiritual exaltation he has the actual divine universal vision. He is conscious of being in the presence of God. He sees the light of God’s countenance. He is lifted above the ordinary plane of consciousness. He reaches a higher state of consciousness. He has a cosmic or universal understanding. He has developed the cosmic sense. The human soul is revolutionised.
