Kesava Kasmiri's Commentary
When the mind becomes fixed remaining steadfast then equanimity will arise. One with spiritual knowledge in transcendent meditation realises the ultimate truth perceiving God within. Understanding this fully Arjuna desirous of knowing the characteristics of such a being such as the way they talk, walk, sit, etc. requests Lord Krishna to reveal to him what are the signs of one stable in transcendence. How was this state achieved? In the world how does such a one speak and act. How does such a one move about. Arjuna asks this question because these things must be different for one situated in nescience. To remove the doubt that qualities such as these by one of tranquil mind such as Brahma or extremely powerful such as Shiva, in addressing Lord Krishna the vocative Keahava is used by Arjuna. Why is this? The creator and controller of both Brahma and Shiva is Lord Krishna who imparts spiritual knowledge to them. Thus Lord Krishna must be accepted as the sole refuge of all of creation because He is omniscient, omnipotent and omnipresent. This is substantiated in the Vedic scriptures. He who creates Brahma and sends the eternal Vedas to him, He the effulgent and illuminating light of the soul and the mind should be supplicated to in full surrender for those desiring liberation from the material existence. From the forehead of He who was mediating on His inner self, Shiva of the trident was produced. In the smrtis it is said that Ka is the name of Brahma and Shiva is Isa the controller of all the embodied souls in material bodies. Both Brahma and Shiva are manifested from Lord Krishna thus Arjuna has called Him by the name Keshava.
