Two Hindu swamis were in conversation.
One said to the other, "How did you like my latest book, 'The Art of Levitation'?"
His companion replied, "It kept me up all night."
A Hindu devotee asked God, represented by the multi-armed Lord Narayana, this question. "My dear Lord," he said. "I understand that you have innumerable inconceivable potencies. But out of all of them the energy of light seems to be the most amazing. Light pervades the spiritual world, it illuminates the material universes, and life is impossible without it." He continued, "I would like to know how you make it work."
"Oh, that's easy," was the reply. "Many hands make light work."
