09. Transformation of the Physical (2)
You have not understood. I was answering the statement that scientists don’t attach any value to sex-gland product and think it is only of use for an external purpose. Many scientists on the 
contrary consider it a base of productive energy; among other things it plays a part in artistic and poetic production. Not that artists and poets are anchorites and Brahmacharis but that they have a powerful sex-gland activity, part of which goes to creative and part to (effectual or ineffectual) procreative action. On the latest theory and yoga theory, the procreative part would be retas, the creative part the basis of ojas. Now supposing the poet or artist to conserve his retas and turn it into ojas, the result would be an increased power of creative productivity.
