Swami Chinmayananda Commentary
The REAL is that which envelops everything that exists, and which is the very stuff and substance of all the worlds of perceptions, which we experience. Different mud-pots, each different in form, shape and colour, may have different names according to the things they contain or according to the purpose for which they are used. Though each of them has thus a different name, yet, all of them are, we may say, enveloped by — or permeated with one and the same stuff, the mud, without which none of the pots can exist. From mud they came; in mud they exist; and when they are destroyed, their names and forms shall merge back to become mud. All the mud-pots are enveloped by mud which is the Reality holding the world of mud-pots together.
Similarly, the world of finite changes is entirely permeated through and through and enveloped by the REAL, the Changeless. And Bhagawan adds that there is no possibility of this REAL, even for a moment, ever getting destroyed, even by a fraction.
WHAT THEN IS THE UNREAL (ASAT) WHOSE EXISTENCE IS NOT CONSTANT? LISTEN:
Adi Sankara Commentary
Tu, but — this word is used for distinguishing (reality) from unreality; tat viddhi, know That; to be avinasi, indestructible, by nature not subject to destruction; what? (that) yena, by which, by which Brahman called Reality; sarvam, all; idam, this, the Universe together with space; is tatam, pervaded, as pot etc. are pervaded by space. Na kascit, none; arhati, can; kartum, bring about; vinasam, the destruction, disappearance, nonexistence; asya, of this avyayasya, of the Immutable, that which does not undergo growth and depletion. By Its very nature this Brahman called Reality does not suffer mutation, because, unlike bodies etc., It has no limbs; nor (does It suffer mutation) by (loss of something) belonging to It, because It has nothing that is Its own. Brahman surely does not suffer loss like Devadatta suffering from loss of wealth. Therefore no one can bring about the destruction of this immutable Brahman. No one, not even God Himself, can destroy his own Self, because the Self is Brahman. Besides, action with regard to one’s Self is self-contradictory. Which, again, is that ‘unreal’ that is said to change its own nature? This is being answered:
