Srila Bhaktisiddhanta Sarasvati Thakura says that the original Personality of Godhead, Krsna, is the Supreme Personality of Godhead, and His expansions are also called the Personality of Godhead. However, Krsna is the original Supreme Personality of Godhead. Speculative philosophers and mystic yogis also meditate upon the form of Krsna, but this form is not the form of the original Supreme Personality of Godhead. Such a Bhagavan is but a partial representation of the Lord's full potency. Nonetheless, He has to be understood to be the Supreme Personality of Godhead. To clarify this matter, one should simply understand that Krsna, the son of Nanda Maharaja in Vrndavana, the friend of the cowherd boys and lover of the gopis, is actually the original Supreme Personality of Godhead. He is attained by spontaneous love. Although His expansions are also called the Supreme Personality of Godhead, They are attained only by the execution of regulative devotional service.
