"Everything that we see, or imagine, or dream, we have to perceive in space. This is the ordinary space, called the Mahâkâsha, or elemental space. When a Yogi reads the thoughts of other men, or perceives supersensuous objects he sees them in another sort of space called the Chittâkâsha, the mental space. When perception has become objectless, and the soul shines in its own nature, it is called the Chidâkâsha, or knowledge space. When the Kundalini is aroused, and enters the canal of the Sushumna, all the perceptions are in the mental space." —Vivekananda, Raja Yoga


"In order to pass to a superior Level of Being, it is necessary to cease being what one is. We need to not be what we are. If we continue being what we are, we will never pass to a superior Level of Being."
