Note (return) — SA@NKARA'S INTRODUCTION (continued 4)

To this we make the following reply.—The transformation of the pradhâna might be ascribed to its own nature merely if we really could admit that grass modifies itself in the manner stated by you; but we are unable to admit that, since another instrumental cause is observed. How? 'Because it does not exist elsewhere.' For grass becomes milk only when it is eaten by a cow or some other female animal, not if it is left either uneaten or is eaten by a bull. If the transformation had no special cause, grass would become milk even on other conditions than that of entering a cow's body. Nor would the circumstance of men not being able to produce milk according to their liking prove that there is no instrumental cause; for while some effects can be produced by men, others result from divine action only326. The fact, however, is that men also are able, by applying a means in their power, to produce milk from grass and herbs; for when they wish to procure a more abundant supply of milk they feed the cow more plentifully and thus obtain more milk from her.—For these reasons the spontaneous modification of the pradhâna cannot be proved from the instance of grass and the like.
