Knowledge, knower and knowable –these three do not exist in reality. Self is that stainless consciousness in which this triad appears through ignorance. there is only nondual self awareness in reality.
The knowledge , knower and knowable are present only in waking or dream but they disappear in deep sleep. All ideas of individual experiences of birth,life and death are present only in waking and they disappears in deep sleep. The knower of the appearance and disappearance of the three states is neither the waking entity nor the dream entity because the waking entity is limited to the waking experience and dream entity is limited to dream. The waking is parallel dream and dream is parallel waking. Thus the knower of the three states is neither the waking entity nor the dream entity but the soul ,which is the witness of the three states ,which appears and disappears. The existence of the witness has to be mentally grasped not assumed.
Consciousness, the One and Undifferentiated, which by the manifold application of its powers produces, the dual and non dual experiences [waking/dream/deep sleep] and, in the end, withdraws the three states into itself, is indeed the self—luminous.
The maker of all the three states, self—luminous and all—pervading, Consciousness dwells always in the three states as its formless clay and witness. Consciousness is revealed by the negative way, discriminative wisdom and the Knowledge of Unity based upon reflection. The one who know Consciousness is the true self becomes one with the immortal self.
When there is no ignorance, there is no day or night, neither being nor none—being; the pure Consciousness alone exists. That immutable Reality is the meaning of "Consciousness. From it has proceeded the non dual wisdom.
No one can grasp Consciousness as separate entity apart from duality because it is the formless clay and the witness of the experience of duality thus it cannot be grasped as above, across, or in the middle.
Its form is not an object of vision; no one beholds it with the eyes. They who, through pure intellect and the Knowledge of Unity based upon reflection, realize Consciousness as the true self becomes one with the immortal.
