Bhagavad-Gita: Chapter 11, Verse 25

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

The visvarupa or divine universal form of Lord Krishna was so terrifying of visage that Arjuna overcome with fear and trepidation was unable to determine the points of the compass and what was up and what was down and being completely distraught beseeches Lord Krishna to relieve his distress with the word prasida meaning please be merciful.

Brahma Vaisnava Sampradaya:

Madhvacarya

Madhvacarya's Commentary

Those who have achieved moksa or liberation from material existence are divine beings and enter into one of the abodes of the Supreme Lord Krishna determined by their devotion to Him. The Brahmanda Purana states: That divine liberated beings are not subject to the stringent rules of material existence but enter into it and depart from it according to the desire of their own free will.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

Viewing the phenomenal panorama of forms and terrifying visages in active mode of Lord Krishna's visvarupa or divine universal form which was blazing flames in all directions was terrible and horrifying like the fires of annihilation during the cataclysm at the time of universal destruction. Arjuna being extremely afflicted beseeched Lord Krishna with the word devasa denoting O' Lord of Brahma and Siva and the words jagan-nivasan O' refuge of the universe and then supplicated Lord Krishna with the word prasida or be merciful and return his normal human vision so that he would be able to regain his equilibrium and composure again.

So the Supreme Lord Krishna exhibiting His visvarupa demonstrated how it manifested from Him, functioned through Him and existed within Him. He will now show to Arjuna how by His indomitable will He will bring about the destruction of Duryodhana and all the Kauravas along with all the demons in the guise of kings fighting with them. Also He will also show the destruction of all those possessed of asuric or demoniac nature that may be fighting for kings in the army of the Pandavas, so that Bhumi-devi or Mother Earth will be rid of such a burden. At this time Arjuna began to see with the divine vision bequeathed by Lord Krishna how all the hosts of the Kaurava army met with their destruction and by who although the actual event had not yet transpired.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

Seeing Lord Krishna's visvarupa or divine universal form with terrifying teeth and unlimited mouths blazing conflagrations like the fires of annihilation at the time of universal destruction. Arjuna totally losing his equilibrium was unable to discern in which direction were the meridians north, south, east and west. He beseeches Lord Krishna with the words deva- isa or O' Lord of lords and jagat nivasa O' refuge of the universe and requests Him with the word prasida to be merciful so that he may regain his composure.
