You carry in yourself all the obstacles necessary to make your realization perfect. If you discover a very black hole, a thick shadow, be sure there is somewhere in you a great light. It is up to you to know how to use the one to realize the other.
The language of the Veda itself is sruti, a rhythm not composed by the intellect but heard, a divine Word that same vibrating out of the Infinite to the inner audience of the man who had previously made himself fit fot the impersonal knowledge.
There is nothing mind can do that cannot be better done in the mind's immobility and thought-free stillness. When mind is still, then truth gets her chance to be heard in the purity of the silence.
For the powers of our mind, life, and body are bound to their own limitations, and however high they may rise or however widely expand, they cannot rise beyond them. But still, mental man can open to what is beyond him and call down a Supramental Light, Truth, and Power to work in him and do what the mind cannot do. If mind cannot by effort become what is beyond mind, Supermind can descend and transform mind into its own substance.
One can see light above the head; that indicates a consciousness outside the body. But that itself is not the Truth-Consciousness or Vijnana. But much light descending from there illumines this consciousness.

The ascent to the divine Life is the human journey, the Work of works, the acceptable Sacrifice. This alone is man's real business in the world and the justification of his existence, without which he would only be an insect crawling among the ephemeral insects on a speck of surface mud and water which has managed to form itself amid the appalling immensities of the physical universe.
