namaste Nara.
Thank you for giving an opportunity for an interesting discussion. What do you think about the points about what is real, unreal and in-between in the following dialogue?
721. ShiShya: Is mAyA real or unreal?
722. Guru: You have asked the most difficult question first. mAyA is neither real nor unreal.
723. S: How can that be?
724. G: It is real because we see the effects of PrakRti existing before us.
725. S: It is also not real because, ...
726. G: Being of the nature of transience, it vanishes in due time.
727. S: If something vanishes after a certain time, is it not taken to be real?
728. G: The word 'real' has to be carefully handled. On one side there is the absolute reality of Brahman.
729. S: Because it is ever there and its presence can never be negated or denied.
730. G: Yes. On the other extreme there is an absolute unreality like, say, a hare's horn, or, the son of a barren woman.
731. S: Actually they don't exist at all.
732. G: That is why it is called absolute unreality. The Sanskrit term is “asat”. It is absolute non-existence.
733. S: Then 'sat' means reality?
734. G: In advaita 'sat' means absolute reality, the Sanskrit being “pAramArthika satyaM”.
735. S: What about the reality of the world?
736. G: It comes between 'sat' and 'asat'. It is neither 'sat' nor 'asat'. 'vyAvahArika satyaM' operational reality.
737. S: What about dream reality?
738. G: Dream is real only to the dreamer and during the dream only. It is subjective reality, “prAtibhAsika satyaM”.
739. S: So there are four kinds of reality?
740. G: All that come in between 'sat' and 'asat' are bunched under the term 'mithyA'.
741. S: So 'mithyA' includes both operational reality of the world and the subjective reality of the dream. Is that right?
742. G: Yes, mAyA belongs to the order of reality called 'mithyA'. It is neither 'sat' nor 'asat'.
743. S: The way you have described it implies that the world belongs to the 'mithyA' type of reality.
744. G: Yes. That is why Shankara's famous quote says: “brahma satyaM, jagat mithyA”.
745. S: I have heard it translated as 'Brahman is the reality, the universe is unreal'.
746. G: That translation would be wrong if you mean by 'unreality' the absolute unreality called 'asat'.
747. S: Can you elaborate this further?
748. G: In all cases of 'mithyA', the 'is-ness' is not questionable. But the understanding of 'what it is' is wrong.
