Tapas is reflection on the nature of the universe.
There are halting, imperfect descriptions of that One Supreme. If we are able to recognize the reality of the Supreme, we will not fall into controversial paths; because mystery is mystery and our attitude is one of silent adoration. Our words and minds are unable to comprehend the immense mystery of this universe. That is the attitude the human mind must adopt: the human mind is incapable of comprehending adequately the nature of that Supreme.
If we get back to this religion of truth, truth of universal love, then it will be possible for us to forget our petty difference, our trivialities on which we waste our lives; our bigotries and disputations will all lose their force and significance.
A truly religious man, if he is authentically religious, will feel that every human being has the dignity, has the spark of Divine. Everyone is a fragment of that impersonal Brahmand, the Universe.
