English Translation of Sanskrit Commentary By Sri Shankaracharya's
11.18 Tvam, You; are the aksaram, Immutable; the paramam, supreme One, Brahman; veditavyam, to be known-by those aspiring for Liberation. You are the param, most perfect; nidhanam, repository-where things are deposited, i.e. the ultimate resort; asya visvasya, of this Universe, of the entire creation. Further. You are the avyayah, Imperishable-there is no decay in You; the sasvata-dharma-gopta, Protector (gopta) of the ever-existing (sasvata) religion (dharma). You are the sanatanah, eternal; transcendental purusah, Person. This is me, my; matah, belief-what is meant by me.
