In distributing the "perfection in yoga" leaflet, when people come to your temple you may explain to them the principles of yoga as they are described in the Bhagavad-gita. Such instructions by you may be preceded and followed by Krishna kirtana. If they are interested, you may show them how to sit, concentrating the eyesight on the tip of the nose. The concentration should be on Lord Krishna or Lord Visnu, as is explained in Bhagavad-gita As It Is. So if they come to know about hatha yoga you can show them in the authoritative scriptures how it cannot be successfully practiced in this present age of kali.
Regarding Nectar of Devotion, you needn't bother about it now. We have solved the problem of what is to be done. Purusottama is now typing with the dictaphone, and he will then edit it and send to Rayarama for a final copy. So far as the new book, "Krishna", I have already sent suggestions to Jadurani, and as soon as the pictures are drawn, I will send to you the tapes. In this way the Krishna book will be completed.
I think that because Jadurani is not quite healthy at the present there is no need of overburdening with pregnancy. In her weakness, the child will be a burden for you and her. Also a child born in weak health is always unhealthy. So it is better you wait until the situation improves.
