The Great Goddess as AdyaShakti creates the Three Shaktis : MahaSarasvati, MahaLakshmi and MahaKali from the sound of the three bija mantras : ऐं ह्रीं क्लीं (aim hrim klim) and assigns to them their powers of creation, preservation and destruction in relation to the three gunas : white sattva, red rajas and black tamas. ॐ ऐं ह्रीं क्लीं चामुण्डायै विच्चे ॐ The three aspects of AdyaShakti become the Shaktis of the Trimurti : Brahma, Vishnu and Shiva. .:. In the Devi Bhagavata Purana, the Goddess states in front of the Trimurti that : I am Adi Parashakti, Goddess Bhuvaneshvari. I am the owner of this universe. I am the Absolute Reality. I am dynamic in feminine form and static in masculine form. You are three parts of me. You all are my partial expansions. You have appeared to govern the universe under my jurisdiction. You are the masculine form of Absolute Reality, while I am the feminine form of that Reality. I am beyond form, beyond everything, and all the powers of God are contained within me. You will admit that I am the Eternally Limitless Power. I shall now assign each of you a task. She then commanded : Brahma ! You will be generator of the universe; the Goddess Sharada is your Shakti, my form by which I will be recognized as the Goddess of Wisdom and the primeval sound. Lord Brahma, this Goddess will be with you when you create the universe. She continued : Lord of Lords, Narayana ! You are the Supreme, Immortal Spirit. You are formless, yet you take form. I assign you to be the preserver of the universe. You will take a different incarnation in order to save this universe's inhabitants. Oh Narayana ! You are the Supreme of all the deities with form. You have created Lord Brahma, and Brahma will further create thirty-three-thousand other gods and goddesses. My Great Power, Goddess Mahakali, has been born from your mystic sleep. You are the Paramatman. Your consort will be Goddess Shri, who is none other than the incarnation of my light, as without light, one can neither see nor be seen. When life evolves, you will take the form of Vishnu, the one who will perform the task of observing and preserving this universe. Oh Lord Rudra, the Greatest God, you are the personification of time, which is above all. You will perform the task of destroying and regenerating this universe. When you are formless, time stands still. It is due to my power that you become dynamic and are capable of bringing about the destruction and regeneration of this universe. Your consort is Goddess Mahakali, but due to meditation, you will be able to surpass all of my forms. It is then that I will incarnate from your left half in my manifested form. This form will be my truest manifested form. Lord Shiva, She will perform the task of destroying evil and will be your consort. .:. Aum Shakti is used to describe the name of the Goddess when She is without attributes. SOURCE : http://en.wikipedia.org/wiki/Adi_parashakti .:.
