An ancient sage of the Upanishads sent his son out to learn about Brahman, and the child came back, and the father asked, ‘What have you learnt?’
The child replied he had learnt so many sciences. But the father said, ‘That is nothing, go back.’
And the son went back, and when he returned again the father asked the same question, and the same answer came from the child. Once more he had to go back. And the next time he came, his whole face was shining; and his father stood up and declared, ‘Ay, today, my child, your face shines like a knower of Brahman.’
When you have known God, your very face will be changed, your voice will be changed, your whole appearance will be changed. You will be a blessing to mankind; none will be able to resist the rishi. This is the rishihood, the ideal in our religion. The rest, all these talks and reasonings and philosophies and dualisms and monisms, and even the Vedas themselves are but preparations, secondary things. The other is primary.
