IF you do what is right for your class and station, you will reach the better world. Do you not know that you can become Brahma in the body itself ? If you are a learned man, you will show your learning in matters of speech; if a singer, you will sing according to the rules of art; if a Yogi, you will know all about the systems of worship, as they are laid down in the Sastras ; the effort by which meditation is accomplished, the motions of the eyes. Tuka says, You do not need all these things; the saints dwell in the body and yet are free from the body.
