Godhead is a male [the energetic source] and he has his plenary expansion who is female [ the complete energy] she is also an expansion of the Lord's energy. Since She is also an extension of Godhead, She is the feminine aspect of God. God is both male and female. They are One, but Godhead 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) Actually, if we all remained merged or amalgamated into one single force or light, then there is no further need of anything else. There certainly would be no need for the material manifestation to provide the innumerable conditioned souls with the means to seek out the way to satisfy their senses, minds, emotions, desires for self-expression, intellectual pursuits, and on and on. So, similarly, the spiritual world is the manifestation wherein all souls have the opportunity to engage in a multitude of pastimes in loving relationships in full spiritual variety, without the many hindrances we find in this material world. The only difference is that the spiritual world is centered around the Supreme Being. And that Supreme Personality has expanded Himself into Radharani for exhibiting the supreme loving relationship, in which so many others assist Them. YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY In the Brihad-Gautamiya Tantra, Radharani is described as follows: devi krishna-mayi prokta radhika para-devata sarva-lakshmi-mayi sarva kantih sammohini para "The transcendental goddess Srimati Radharani is the direct counterpart of Lord Sri Krishna. She is the central figure for all the goddesses of fortune. She possesses all the attractiveness to attract the all-attractive Personality of Godhead. She is the primeval internal potency of the Lord." To explain further, Srimati Radharani is also the source of the other goddesses, who are expansions of Her. Just as Lord Krishna is the source of all other expansions and incarnations of God, Radharani is the source of all other expansions of the energies of God, the shaktis, or other goddesses. Thus, Vishnu, Rama, even Shiva are all expansions of the one Supreme Being, and similarly Lakshmi, Sita, and even Durga are all expansions of this Supreme Feminine form of God, Radharani. It is explained that the beloved consorts of Lord Krishna are of three kinds, namely the goddesses of fortune or Lakshmis, His queens, and the milkmaids of Vraja called the gopis. All of them proceed from Radharani. The Lakshmis are partial manifestations, or plenary portions, of Srimati Radharani, while the queens in Vaikuntha and in Dvaraka are reflections of Her image. The Vraja-devis or gopis are Her expansions and assist in the increase of rasa, or the divine loving pastimes. Among them there are many groups that have various sentiments and moods, which help Lord Krishna taste the sweetness of the rasa dance and other pastimes. (Cc.Adi-lila. 4. 75-81) "Among the gopis of Vrindavana, Srimati Radharani and another gopi are considered chief. However, when we compare the gopis, it appears that Srimati Radharani is most important because Her real feature expresses the highest ecstasy of love. The ecstasy of love experienced by the other gopis cannot be compared to that of Srimati Radharani." (Ujjvala-nilamani 4.3 of Srila Rupa Gosvami) YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY Godhead is the primeval Lord, the original Personality of Godhead, so He can expand Himself into unlimited forms with all potencies. They are no different from Him, but may exhibit differences in form and function. Godhead first expands Himself into Baladeva, or Balarama, who is considered Krishna’s second body and brother. Balarama assists in Godhead’s innumerable spiritual pastimes in both the spiritual and materials realms. Lord Balarama is also Lord Sankarshana, the predominator of the creative energy. He creates and is also the shelter of the material and spiritual worlds. By the will of Godhead and the power of the spiritual energy, Lord Balarama creates the spiritual world, which consists of the planet Goloka Vrindavana [the supermost spiritual planet] and the Vaikuntha planets [in the spiritual sky]. (Chaitanya-caritamrita, Madhya-lila, 20.255-6) Lord Balarama especially assists Godhead in the creation of the material world.
