I wish to see You in that form – with crown, mace and discus. Therefore, O Thousand-armed,
O Universal form, become that four-armed form itself.
As Arjuna earlier wished to see the Universal form, here now he yearns to be graced by the four-armed form. Viśva-rūpa led Arjuna to understand the greatness and glory of Krishna, the Supreme. It expanded his mind, and grew in him devotion, which prompted him to prostrate repeatedly before Krishna, whom he found all-pervading.
Unable to bear the Viśva-rūpa any more, Arjuna asks Krishna to withdraw it and show his four-handed graceful form. But he does not speak about the conch and lotus. True, both are not relevant to Kurukshetra. The freedom a guileless mind enjoys in interacting with Krishna so closely shines exquisitely.
