Shaktas worship Goddess as Mother Shakti, in different forms. These forms may include Kali, Parvati/Durga, Lakshmi and Saraswati. The branch of Hinduism that worships the goddess, known as Devi, is called Shaktism. Followers of Shaktism recognize Shakti as the power that underlies the male principle, and Devi is often depicted as Parvati (the consort of Shiva) or as Lakshmi (the consort of Vishnu). She is also depicted in other manifestations, such as the protective Durga or the violent Kali. Shaktism is closely related with Tantric Hinduism, which teaches rituals and practices for purification of the mind and body.
