The Rig Veda, the oldest book on the planet, tries to describe the mystery by singing hundreds of thousands of hymns and yet it comes to the famous conclusion: Neti, Neti, meaning 'not this, not this'. Freedom, Enlightenment, Love, though the topic of Advaita Vedanta remains untouched by the wondering mind, and yet is the light by which the mind sees. Only when the mind stops does Consciousness behold Itself. Then 'Consciousness knows the Truth and the Truth sets itself Free'. You are this Truth, the Is-ness joyously radiating as the Light of this Moment.
