The sixth form of the divine mother is known as Katyayani. In ancient times there was a Rishi by the name of Katyayan. The rishi was completely devoted to the form of worship of the divine mother. After years of tapas when the divine mother was pleased she appeared before him and asked him for a boon. He asked her to be born in her home as her daughter. Usually the daughters are known by their own names but here the divine mother herself chose to be known by the name of her devotee and father choosing the name Katayayani for herself.
This form of the divine mother is especially worshiped as a form that satisfies desire. It is said that the Gopis (the girls who fell in love with god Krishna) and Rukmini of Vrindaban worshipped this form so that they could marry god Krishna and this form of the divine mother was Rukmini's favourite form (Isht). By the blessings of the divine mother in the form of Katyayani they all married her. God Krishna had a huge number of wives.
Iccha shakti or the power of will is the force that manages life. The mind is the cause for birth and death. Katyayani is the power of mind. She is known as the Kriyatmak shakti (energy of the processes of life) of Prakriti (Nature) that manages and runs the mind. Desires are born of the mind and the mind is the cause of its own deviations. In the path of spirituality and devotion, the mind itself becomes a hindrance to achieve spiritual results. Worship of the divinity Katyayani makes the mind become devoted and one pointed. She makes the mind energetic and therefore gives life to the Jiva (individual soul).
The form of the divine mother is divine, calm, fair(complexioned), three-eyed, having eight hands, seated on a lion. Her mantras are
