Brahmacharni is the second phase of nine Durgas. She is venerated on the 2nd day of Navratri. Here “Brahma” means penance. So, Brahmacharini is one who practices penance.
Bramha refers to the meditative aspect of Brahmacharini and is always depicted as pious women or Sannyasin. She is also worshiped as goddess Tara and is associated with the pious form of Hindu Goddess Shakti. She is believed to be that aspect of Mother Goddess Devi, which was present in Sati and Goddess Parvati, when they both did intense austerities to get Lord Shiva as husband.
Brahmacharini is known for knowledge of scriptures, essence and penance. She is depicted with prayer beads in her right hand and Kamandal in left hand.
