Sripada Sankaracarya explicitly says, You fools, just worship Govinda and that Bhagavad-gita spoken by Narayana Himself, yet foolish people still conduct their research work to find out Narayana; consequently they are wretched, and they waste their time for nothing. Narayana is never wretched nor daridra; rather, He is worshiped by the goddess of fortune, Laksmi, as well as by all living entities. Sankara declared himself to be Brahman, but he admits Narayana, or Krsna, to be the Supreme Personality who is beyond the material creation. He offers his respects to Krsna as the Supreme Brahman, or Parabrahman, because He (Krsna) is worshipable by everyone. Only the fools and enemies of Krsna, who cannot understand what the Bhagavad-gita is (though they make commentaries on it), say, It is not the personal Krsna to whom we have to surrender ourselves utterly, but the unborn, beginningless Eternal who speaks through Krsna. Fools rush in where angels fear to tread. Whereas Sankara, the greatest of the impersonalists, offers his due respects to Krsna and His book the Bhagavad-gita, the foolish say that we need not surrender to the personal Krsna. Such unenlightened people do not know that Krsna is absolute and that there is no difference between His inside and outside. The difference of inside and outside is experienced in the dual, material world. In the absolute world there is no such difference, because in the absolute everything is spiritual (sac-cid-ananda), and Narayana, or Krsna, belongs to the absolute world. In the absolute world there is only the factual personality, and there is no distinction between body and soul.
