They are basically states of insight into the depths of truth, unhindered by the discursive intellect. They are illuminations and revelations about the universe at large, full of significance and importance... they carry with them a curious sense of authority for after-time.'
' An intellect which at a given instant knew all the forces acting in nature, and the position of all things of which the world consists... would embrace in the same formula the motions of the greatest bodies in the universe and those of the slightest atoms; nothing would be uncertain for it, and the future, like the past, would be present to its eyes.'
Vast is That, divine, its form unthinkable; it shines out subtler than the subtle: very far and farther than farness, it is here close to us, for those who have the vision it is here even in this world; it is here, hidden in the secret heart.-
Mundaka Upanishad 3.1.7
