Dear Alok, There is no being in the unreal and there is no being in the real. – In this Sloka, what is meant by bhavah? I feel the meaning is this: Truth will have some representation ( sense). Where illusion (asatah) never has any representation. So anything that anyway manifested is true, untrue can never manifest. Am I right? Please clear my understanding.

This shloka from the second chapter of the Srimadbhagawatgita implies that ‘whatever is true (sat) is permanent. It will always be there (bhav). Whereas that which is not true is anyways non-existent. It cannot remain. It is in the sense of what is permanent and what is temporary, rather than illusory, unless we use the word illusory as an appearance. 

Of course, nothing can manifest out of nothing. So everything that has come into existence has come out of Truth. What seems illusory also has its origin in Truth. 

Affectionately,

Alok Da

(follow-up question:)

So there’s nothing as Illusion. Because even for a mirage to look like water, or a rope to look like a snake, there should be water and a snake in truth to make you see them as water and a snake. So, absolutely, Truth only exists, directly or obscurely.

Yes. There is Truth and its distortion. That is what illusion actually means, and not as something non-existent, for that is an impossibility. 

Affectionately,

Alok Da
