135. Nirmalā
Devi is free from all impurities.
The possibility of an impurity arises only when a pure entity is getting mixed up with another impurity, which is not pure by definition.
What is happening in the case of Devi? Pure consciousness is all the time getting mixed or separated from pure consciousness. There is no second entity. Even the so-called existence is a property of consciousness, as consciousness is the property of existence. Even though the words consciousness and existence seem to be different words, each is the meaning of the other. This is now the śastras describe the union of Śiva and Śakti as being inseparable from each other, and out of their union flows the eternal bliss called the Ānanda. Thus Sat (existence) Cit (consciousness) and Ānanda (bliss) are considered to be of the nature which defines God in the abstract form, devoid of all names and perceived forms.
