Declaring the unparalleled supremacy of God, all the scriptures state
aham evāsam evāgre nānyat kiñchāntaraṁ bahiḥ
(Bhāgavatam 6.4.47)[v15]
“I, the Supreme Lord, am everything that exists. There is nothing beyond me and nothing higher than me.”
tvamomkāraḥ parātparaḥ
(Vālmīki Ramayan)[v16]
“The primordial sound “Om” is your manifestation. You are greater than the greatest.”
vāsudevaḥ praḥ prabhuḥ
(Nārad Pañcharātra)[v17]
“Shree Krishna is the ultimate Supreme Lord.”
na devaḥ keśhavāt paraḥ
(Nārad Purāṇ)[v18]
“There is no god higher than Lord Krishna.”
vidyāt taṁ puruṣhaṁ param
(Manu Smṛiti 12.122)[v19]
“God is the highest and ultimate personality that exists.” However, as was explained previously (commentary of verse 11.24), when love swells immensely it makes the lover forget the formal position of the beloved. Thus, in his extreme love for Shree Krishna, Arjun had shared many intimate memorable moments with him, blissfully oblivious of his supreme position.
Having seen the universal form of God, Arjun is now painfully aware that Shree Krishna is not merely his friend and comrade-in-arms, but is also the Supreme Divine Personality, whom even the
devatās, gandharvas, siddhas,
etc. venerate. Thus, he feels regret for the disrespect he thinks he may have shown toward Shree Krishna by audaciously looking upon him as a mere friend. As an indication of respect, those who are venerated are not called by their first names. He is worried that due to excessive familiarity, he had put himself on equal status with God and had presumptuously addressed him with affectionate vocatives, such as “My friend,” “My dear buddy,” and “O Krishna.” So he implores forgiveness for whatever he may have done in forgetfulness of the divinity of Shree Krishna’s personality.
