Shakti that you worship for nine days as Navratri resides in your body, in your psycho-physical system, in the mooladhara as the Tripura Sundari, Rajarajeshwari and the whole of the practice of Tantra is to win over this Devi and take her carefully to the sahasrara where she meets her Lord who is always sitting. When this happens then the ecstasy of Saundarya happens and the Yogi is no longer an ordinary human being.
