Text 16 

vaktum arhasy asesena
divya hy atma-vibhutayah
yabhir vibhutibhir lokan
imams tvam vyapya tisthasi

Translation

Please tell me in detail of Your divine opulences by which You pervade all these worlds. 

Commentary by Srila Prabhupada 

In this verse it appears that Arjuna is already satisfied with his understanding of the Supreme Personality of Godhead, Krishna. By Krishna’s grace, Arjuna has personal experience, intelligence and knowledge and whatever else a person may have through all these agencies, and he has understood Krishna to be the Supreme Personality of Godhead. For him there is no doubt, yet he is asking Krishna to explain His all-pervading nature. People in general and the impersonalists in particular concern themselves mainly with the all-pervading nature of the Supreme. So Arjuna is asking Krishna how He exists in His all-pervading aspect through His different energies. One should know that this is being asked by Arjuna on behalf of the common people.

Commentary by Sri Visvanatha Cakravarti Thakur

"It is difficult to understand the truth about you. Therefore, I want to know about your vibhutis. Your vibhutis are very attractive (divya). You should speak about them fully."

"But it is impossible to speak of all of my vibhutis fully."

"Speak about those vibhutis by which you spread yourself in this world."
