Sridhara Swami's Commentary
Having humbly beseeched Lord Krishna for full forgiveness, Arjuna now
reveals his heart in this verse and the next explaining that by seeing the
visvarupa or divine universal form, that had never been seen before and
which possesses unlimited grandeur and power he was ovejoyed and thrilled
but at the same time his mind was agitated and disturbed by the fearful
aspect of it. Feeling trepidation Arjuna requests Lord Krishna to please
revert back to the human looking form of his friend that he is accustomed
to always seeing.
