Well, you just patiently do one thing — set about collecting everything that books, beginning with the Rig-Veda down to the most insignificant of Puranas and Tantras, have got to say about creation and annihilation of the universe, about race, heaven, and hell, the soul, consciousness, and intellect, etc., the sense-organs, Mukti, transmigration, and suchlike things. No child's play would do, I want real scholarly work. The most important thing is to collect the materials. My love to you all.
