B.G 13.13

I will explain what is to be known, which, when understood, leads to immortality. That supreme Brahman, without beginning, is described as neither existent nor non-existent.

Gīta Bhāshya 13.13

The declarative phrases "Supreme Brahman", "he who", and "from whose influence" indicate the information being provided is to gain definitive understanding. 'anādimat' - devoid of beginning and also devoid of material body.

It is declared as "Supreme Brahman" and "he who" to provide definitive understanding. Also, phrases such as 'yatprabhāva', i.e. "from whose influence" is used. The word 'anādimat' conveys He is devoid of beginning and also material body. Otherwise, just the word 'anādi' would have sufficed.

Gīta Tātparya 13.13

anādimat - indicates not only the Lord as having no beginning but also as the ultimate cause. Testimonials are provided that declare Lord Janardana as the Supreme Brahman due to the fullness of qualities. He transcends both form and formlessness, and thus is described as neither existing nor non-existing. He is known through the Vedas and is beyond the grasp of men due to limitation in their capabilities.

When it is stated as 'without beginning' (anādi), there could be a doubt that it implies Brahman himself is not the cause. To address this doubt, it is clarified by saying 'having no beginning' (anādimat).

"Primarily, Lord Janardana is the Supreme Brahman due to the fullness of qualities. He transcends both form and formlessness, and thus is described as neither existing nor non-existing."

- stated thus as well.

"The Lord's form is beyond existence and non-existence, comprehensible yet unknowable. He is known through all the Vedas and is beyond the grasp of men due to limitation in their capabilities. The distinct Lord Vishnu is beyond existence and non-existence, and is immutable."

- stated thus as well.
