Radha-Krishna are collectively known within Hinduism as the combined forms of feminine as well as the masculine realities of God.
She is also considered in Vaishnavism as the total feminine energy and also as the Supreme Lakshmi (Adi-Lakshmi). Various devotees worship her with the understanding of her merciful nature as the only way to attain Krishna. Radha is also depicted to be Krishna himself, split into two, for the purpose of his enjoyment. Krishna enchants the world, but Radha enchants even Him. Therefore She is the supreme goddess of all.
