Text 16

वक्तुमर्हस्यशेषेण दिव्या ह्यात्मविभूतयः ।
याभिर्विभूतिभिर्लोकानिमांस्त्वं व्याप्य तिष्ठसि ॥१६॥

vaktum arhasy aśeṣeṇa
divyā hy ātma-vibhūtayaḥ
yābhir vibhūtibhir lokān
imāḿs tvaḿ vyāpya tiṣṭhasi

Translation:

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

Purport:

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.
