Divine Mother Parashakthi is "Divine Pure Eternal Consciousness" manifested as Shiva Shakthi and formed a Nada Bindu (sound and spiritual light), which separated into Shiva and Shakthi.
The Mother Parashakthi Sanctum (Sannidhi) is also graced by the presence of the Maha Meru which now confers the status of RajaRajeswari/ Bhuvaneswari to this Sannidhi.
