हिंदी अनुवाद - स्वामी रामसुख दास जी ( भगवद् गीता 7.26)
।।7.26।।हे अर्जुन जो प्राणी भूतकालमें हो चुके हैं जो वर्तमानमें हैं और जो भविष्यमें होंगे उन सब प्राणियोंको तो मैं जानता हूँ परन्तु मेरेको कोई (मूढ़ मनुष्य) नहीं जानता।


English Translation of Sanskrit Commentary By Sri Shankaracharya's
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.

English Translation of Ramanuja's Sanskrit Commentary
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:
