Following is the interpretation of three Gunas and the bodies from Vivek Choodamani.
120. This Undifferentiated, spoken of as the compound of the three Gunas, is the causal body of the soul. Profound sleep is its special state, in which the functions of the mind and all its organs are suspended.
121. Profound sleep is the cessation of all kinds of perception, in which the mind remains in a subtle seed-like form. The test of this is the universal verdict, "I did not know anything then".
122. The body, organs, Pranas, Manas, egoism, etc., all modifications, the sense-objects, pleasure and the rest, the gross elements such as the ether, in fact, the whole universe, up to the Undifferentiated – all this is the non-Self.
123. From Mahat down to the gross body everything is the effect of Maya: These and Maya itself know thou to be the non-Self, and therefore unreal like the mirage in a desert.
