Brahmacharini means a devoted female student who lives in an Ashrama with her Guru along with other students. It is also the name of the second aspect of the goddess Durga (Parvati). The goddess is worshipped on the second day of Navratri. In this avatar, Durga embodies tapa or penance. The name Brahmacharini is derived from two words – “Brahma” here means tapa or penance and “Charini” means an ardent female follower.
