Devi Upanishad

 I bow to Thee, Goddess, Thou dispeller of gravest fears, vanquisher of obstacles; Thou wearer of great mercy’s form.

Brahma and others know not Her essence; so is She called the Unknowable.

She has no end; so is She called the Endless.

She is not grasped and so is She called the Incomprehensible.

Her birth is not known and so is She called the Unborn.

She alone is present everywhere, and so is She called the One.

She alone wears all forms, and so is She called the Many.

For these reasons is She called the Unknowable, the Endless, the Incomprehensible, the Unknown, the One and the Many.

The Goddess is the source of all mantras: Of all the words the knowledge is Her form. Her conscious form transcends all cognitions; She is the witness of all emptiness.

Beyond Her is nothing; renowned is She as unapproachable; afeared of life, 

I bow to the inaccessible One, bulwark against all sins; the Pilot who steers me across the sea of worldly life.
