Moola Nakshatra is described in Vedic literature as Moolabharhini and Vichriti, as the root cause of demons was believed to be abolished in this Nakshatra. The word Moola means “a bunch of roots,” and also signifies foundation or origin.
Moola is recognised as the “tail of a lion,” which corresponds with its appearance resembling a bunch of roots tied together.
The ruling deity of Moola is cited differently in various Vedic contexts, with Nirriti, Prajapati, and the Pitars being mentioned alternatively. Later traditions primarily associate Moola with Nirriti, who is considered a demonic figure.
In contrast, the Rigveda and Atharvaveda describe Nirriti as the deity of destruction, annihilation, disease, misfortune, and literal death. Nirriti is depicted similarly to Yama, dispensing intense suffering.
The Kalika Purana, however, establishes Nirriti as Mother Earth, who gives rise to and sustains all kinds of beings, including those possessing virtues and wisdom.
