SB 3.2.9

In the Vedas it is said that the Supreme Lord or the Paramatma cannot be understood simply by the strength of one's erudition or power of mental speculation: nayam atma pravacanena labhyo/ na medhaya na bahuna srutena. He can be known only by one who has the mercy of the Lord. The Yadavas were all exceptionally learned and experienced, but in spite of their knowing the Lord as the one who lives in everyone's heart, they could not understand that He is the original Personality of Godhead. This lack of knowledge was not due to their insufficient erudition, but it was due to their misfortune. In Vrndavana, however, the Lord was not even known as the Paramatma because the residents of Vrndavana were pure unconventional devotees of the Lord and could only think of Him as their object of love. They did not know that He is the Personality of Godhead. The Yadus or the residents of Dvaraka, however, could know Lord Krsna as Vasudeva or the Supersoul living everywhere, but not as the Supreme Lord. As scholars of the Vedas, they verified the Vedic hymns: "eko devah . . ." "sarva-bhutadhivasah . . ." "antaryami . . ." and "vrsninam para-devata. . . ." The Yadus, therefore, accepted Lord Krsna as the Supersoul incarnated in their family, and not more than that.
