Link:- The Lord, in the previous three verses, called upon Arjuna to behold His cosmic form, four times by using the term 'Pasya' (see). But Arjuna in spite of his best efforts could behold nothing. So the Lord (knowing the cause of Arjuna's failure to see that form), bestowing upon him a gift of divine vision, for him, to behold His cosmic form.
na tu mah sakyase drastumanenaiva svacaksusa
divyam dadami to caksuh pasya me yogamaidvaram
But you cannot view Me, with these human eyes of yours; therefore I grant you divine vision with which, behold My divine
power of Yoga. 8
An Important Fact
Na tu mam iakyase drastumanenaiva svacaksusa:- Lord Krsna, knew that His transcendent form, could not be seen, with ordinary human eyes, because their power is very poor and limited, and these can see, only the objects of nature such as men, beasts and birds etc., but cannot behold His form, which is beyond the reach of senses, mind and intellect.
Divyam dadami te caksuh pasya me yogamaisvaram:- By His power of Yoga, the Lord bestowed upon Arjuna the divine faculty, in order to enable him to have a vision of the spiritual objects, beyond the reach of sense-organs, as well as, His cosmic form, with his human eyes.
The term, 'Pasya', has two meanings—to see with intellect (discrimination), and to see with one's eyes. In the verse of the ninth chapter, it is related perceiving with intellect, while here, the context is of seeing with eyes.
Suppose the word 'Gita', is written somewhere. An illiterate person, just notices black marks, a man having knowledge of letters, can see the letters, but an educated person who is a scholar, and who has studied the Gita, thoroughly, after having a look at the word 'Gita', thinks of its chapters, verses and its gospel etc.
