Query: HEAVY!

WOW! This slim volume is very heavy(!), did I say heavy? This work is phenomenal(!) but(whoa unto you)VERY abstract...trust me when I say this. It must be read very, very slowly and each paragraph must be contemplated upon for quite sometime. Wei is not for the faint-hearted and not a starting point for the beginner of non-dualistic thought. Please read elsewhere gentle reader, and when you are ready - really ready for truth spoken at the most inclusive and abstruse level then - and only then - prepare yourself for a feast which will de-cloak all that you have held near and dear about what you erroneously have concluded about "reality".
