Self is Undivided Awareness.

Everything is not only interlinked; everything is Self. It is Self which experiences itself as itself. Any sense of separate individuality is merely Self perceiving itself as separate individuals not to feel alone. Aloneness is indeed the originating cause and Companionship is rightfully so the purpose. The purpose of Self is not to feel alone. It is not good to be alone. The answer to the question - what is Self? - is undivided awareness. Self is Eternal, Deathless and Timeless.
