kasmāc ca te na nameran mahātman
garīyase brahmaṇo ’py ādi-kartre
ananta deveśa jagan-nivāsa
tvam akṣaraṁ sad-asat tat paraṁ yat
Arjuna especially mentions that Kṛṣṇa is greater than Brahmā because Brahmā is created by Him. Brahmā is born out of the lotus stem grown from the navel abdomen of Garbhodaka-śāyī Viṣṇu, who is Kṛṣṇa’s plenary expansion; therefore Brahmā and Lord Śiva, who is born of Brahmā, and all other demigods must offer their respectful obeisances. It is stated in Śrīmad-Bhāgavatam that the Lord is respected by Lord Śiva and Brahmā and similar other demigods. The word akṣaram is very signiﬁcant because this material creation is subject to destruction but the Lord is above this material creation. He is the cause of all causes, and being so, He is superior to all the conditioned souls within this material nature as well as the material cosmic manifestation itself. He is therefore the all-great Supreme.
