वेदाहं समतीतानि वर्तमानानि चार्जुन।
भविष्याणि च भूतानि मां तु वेद न कश्चन।।7.26।।
।।7.26।। हे अर्जुन पूर्व में व्यतीत हुए और वर्तमान में स्थित तथा भविष्य में होने वाले भूतमात्र को मैं जानता हूँ परन्तु मुझे कोई भी पुरुष नहीं जानता हैं।।
Lord Krishna explains that for Him there is never any illusion; but the embodied beings without His grace emanating through the bonafide spiritual master in authorised disciplic succession will find it impossible to extricate themselves from maya or illusory impressions superimposed upon the mind. It should be clearly understood that no one can know Lord Krishna by their own efforts regardless how great. He is only known by His own desire. Now begins the summation. As much as Lord Krishna is known to Himself none other can know Him. Brahma the demigod responsible for material creation and Shiva the demigod responsible for material destruction, by His grace know Him partially to some extent according to their ability and gradation. The Katha Upanisad I.II.XXIII is categorical in its declaration that: The Supreme Lord cannot be attained by instruction or by intelligence or even by constant hearing about. Whom the Supreme Lord Himself chooses, only is able to attain Him and none other. Only to the one He chooses doe He reveal His rupa form, guna or qualities and lila His phenomenal pastimes.
