The transcendental goddess Srimati Radharani is the direct counterpart of Sri Krsna. She is the central figure for all the goddesses of fortune. She possesses all attractiveness to attract the all-attractive Personality of Godhead. She is the primeval internal potency of the Lord."

Additional information about Sri Radha is given in the Rg-parisista (the supplement to the Rg Veda): radhaya madhavo devo madhavenaiva radhika / vibhrajante janesu. "Among all persons, it is Sri Radha in whose company Lord Madhava is especially glorious, as She is especially glorious in His."
