Srimati Radharani is the Supreme Goddess. She is most always seen with Lord Krishna. It is described that She is the Chief Associate and devotee of Lord Krishna, and topmost of all Goddesses. Her name means the She is the most excellent worshiper of Lord Krishna. However, She is also an expansion of the Lord's energy. Since She is also an extension of Krishna, She is the feminine aspect of God. Thus, in the Gaudiya Vaishnava tradition, God is both male and female. They are One, but Krishna expands into two, Himself and Radharani, for the sake of divine loving pastimes. If They remained as One, then there is no relationship, there are no pastimes, and there can be no dynamic exchange of love. (Caitanya-caritamrita, Adi-lila, 4.55-56)
