Mahavidyas

Mahavidyas (Great Wisdoms) or Dasha-Mahavidyas are a group of ten aspects of Adi Parashakti in Hinduism. After the decline of Buddhism in India, Sakta and Buddhist goddesses were combined to form this list of ten.

The development of Mahavidyas represents an important turning point in the history of Shaktism as it marks the rise of Bhakti aspect in Shaktism, which reached its zenith in 1700 CE. First sprung forth in the post-Puranic age, around 6th century C.E., it was a new theistic movement in which the supreme being was envisioned as female. A fact epitomized by texts like Devi-Bhagavata Purana, especially its last nine chapters (31-40) of the seventh skandha, which are known as the Devi Gita, and soon became central texts of Shaktism.

The name Mahavidyas comes from the Sanskrit roots, with meaning 'great' and vidya meaning, 'revelation, manifestation, knowledge, or wisdom.

Shaktas believe, "the one Truth is sensed in ten different facets; the Divine Mother is adored and approached as ten cosmic personalities," the Dasa-Mahavidya ("ten-Mahavidyas"). The Mahavidyas are considered Tantric in nature, and are usually identified as:

The Mahabhagavata Purana and Brhaddharma Purana however, list Shodashi (Sodasi) as Tripura Sundari, her another name. The Guhyatiguyha-tantra associates the Mahavidyas with the ten Avatars of Vishnu, and states that the Mahavidyas are the source from which the avatars of Vishnu arose. All ten forms of the Goddess, whether gentle or terrifying, are worshiped as the universal Mother. All ten forms of the Goddess is concluded and worshipped in the Sri Chakra and Tripura Sundari is considered as the Adi Para Sakthi.
