BG 7.26

O Arjuna, as the Supreme Personality of Godhead, I know everything that has happened in the past, all that is happening in the present, and all things that are yet to come. I also know all living entities; but Me no one knows.

7.26. O Arjuna, I know the beings that are gone off, that are present and are yet to be born; but no one, knows Me.

7.26 I know, O Arjuna, all beings in the past, the present and the future; but they do not know Me.

7.25-26 Naham etc. Vadaham etc. I am not perceivable to all. But the actions themselves, if performed, would beget emancipation at the time of dissolution [of the world]. otherwise, how does the total dissolution come to be there ? When this doubt arises, [the Bhagavat] commences [to answer] as :

7.26 I know all being that have passed away, those that live now and those that will hereafter. But no one knows Me. Among the beings existing in the three-fold divisions of time whom I look after, no one understands Me as of the nature described and as Vasudeva incarnated to be a refuge for all. So no one resorts to Me. Therefore, the one who knows Me really (Jnanin) is extremely difficult to be found. Such is the meaning. So also:

7.26 O Arjuna, aham, I, however; veda, know; samatitani, the past beings; and vartamanani, the present. I know ca, also; bhavisyani, the future; bhutani, beings. Tu, but; na kascana, no one; veda, knows; mam, Me. Except the one person who is My devotee and has taken refuge in Me, no one adores Me, jus because he does not know My reality. 'What, again,is the obstruction to knowing Your reality, being prevented by which the creatures that are born do not know You?' In anticipation of such a estion, the Lord says this:

7.26 I know all beings, O Arjuna, past, present and those to come; but no one knows Me.

7.26 O Arjuna, I know the past and the present as also the future beings; but no one knows Me!
