Link:- In the next verse, Sanjaya describes to Dhrtarastra the nature of the divine cosmic body, revealed by the Lord of Arjuna
evamuktva taco rajanmahayogesvaro harih
darsayamssa parthaya paramam rupamaisvaram
O King, having spoken thus, the Supreme Lord of Yoga, Hari (Krsna), showed to Partha (Arjuna) His supremely divine form (Viswarupa). 9
Evamuktva tato rapamalsvaram:-'Evamuktva', denotes the topic of the preceding verse, when the Lord declared, "You can't see Me with your human eyes, therefore I give you divine eyes. With these behold My divine power, of Yoga."
In the fourth verse, Arjuna addressed Lord Krsna as the Lord of Yoga, while here Sanjaya addresses Him as the Supreme Lord of Yoga. It means, that the Lord revealed His hundreds and thousands of multifarious divine forms, while Arjuna wanted to behold only one. If a devotee, has a little inclination towards the Lord, He by His limitless power, enhances that inclination.
The form, which was called by Arjuna, in the third verse, as divine, has been called by Sanjaya here, as supremely divine. It means that the Lord Krsna, the great Lord of all the Yogas, reveals such an uncommon, singular, and wonderful Cosmic form, that even such a valiant, steady and self-controlled warrior, as Arjuna, who has been granted divine vision by the Lord, has to say it is hard to gaze at (11117), 'My mind is tormented by fear' (11/45), and the Lord had to console him by asking him to be free from fear (11/49).
