ज्ञेयं यत्तत्प्रवक्ष्यामि यज्ज्ञात्वाऽमृतमश्नुते।
अनादिमत्परं ब्रह्म न सत्तन्नासदुच्यते।।13.13।।
।।13.13।। मैं उस ज्ञेय वस्तु को स्पष्ट कहूंगा जिसे जानकर मनुष्य अमृतत्व को प्राप्त करता है। वह ज्ञेय है अनादि? परम ब्रह्म? जो न सत् और न असत् ही कहा जा सकता है।।
The brahman or the spiritual substratum pervading all existence is the brahma referred to here. This is given as a reminder of the dependence of the Supreme Lord Krishna by whose energy everything is transpiring. The word anadimat means without any origin and beginning and denotes that the Supreme Lord is without origin and beginning also. If only anadi was used a doubt might arise that there is an origin for Him and so how can He manifest something without beginning if He is not as well. So the word anadimat is used as a matter of clarification. Due to being complete in fullness with all transcendental attributes the Supreme Lord is called param brahman meaning the Supreme brahman and is both sat or eternal existence and asat or non existence possessing a transcendental spiritual form and formless being without a physical form. Yet since He can be discerned by outward elements such as earth, fire, water etc. and since He is emphatically eulogized in the Vedic scriptures. The resplendent Supreme Lord Krishna, the immutable one is especially known both as sat and asat.
