manyase yadi tacchakyam maya drastumiti prabho
yogesvara taco me tvam darsayhtmanamavyayam
O Lord if You, think that this cosmic form could possibly be seen by me, then, O Lord of Yoga, reveal to me that imperishable form. 4
Prabho:- The term 'Prabho', means Omnipotent. Arjuna uses this vocative 'Prabho', for Lord Krsna to indicate, that He is Omnipotent. So, even if he is not agreeable, the Lord, by His grace and power could enable him, to have a vision of His divine form.
Manyase yadi tacchakyam maya drastumiti:- Arjuna says to Lord Krsna, that even if He does not reveal His divine form to him, he will believe His words, that His form is the same as He has described, but he is not qualified and deserving to behold it. Thus, Arjuna does not doubt the Lord's statement in the least, rather he has full faith in it. So he prays to Him, to reveal to him His divine form, if He thinks it possible for him, to see it.
Yogesvara:- By using the address 'Yogesvara', Arjuna says that He is the Lord of all Yogas (Disciplines), such as the Disciplines of Devotion, of Action, of Meditation, of Knowledge etc. So by His power, He could enable him, to behold His divine Cosmic Form.
Arjuna, in the seventeenth verse of the tenth chapter, used the term 'Yogin' but now he uses the term 'Yogesvara' (the Lord of Yoga) i.e., the Master of all the Yogas, because now there is a lot of change in his attitude, towards the Lord.
Tato me tvam darsayntmanamavyayam:- Arjuna prays to Lord Krsna, to reveal to him His imperishable form, from which infinite universes emanate, in which they remain established, and in which they again merge.
