The One Who cannot be moved.
Niscala is the unmoving, stable, eternal nature of Maa.
She is the cosmic energy, beyond manifestations which are impermanent, moving and transient in nature.
She is the essence of all creation and exists in everything and yet is whole.
This essence of stability, and oneness is experienced by the Sadhak in his intense sadhana for Maa, where it is bestowed by none other than Maa.
She gives one; the ability to stay as unmoving and stable as Namdiswara. A stable Asana, gives prosperity.
Hence the name Niscala.
