It's not about learning, as important as that is.  It's not about becoming, for you already are the Self.  It's just that you don't yet live in the Knowingness of your own Beingness, not all the time.  Not yet.  The One who gives you your own Self — more than this, the One who opens up the power of Consciousness to arise within you, Kundalini — such a one is worthy of this revered title, Guru.
