The Ten Mahavidyas (Daśa Mahāvidyāḥ) are central to the practices of Shakta Tantric tradition. Kamakhya is primarily and equally identified with Durga (especially as Mahiṣāsuramardinī), Kālī, and Ṣoḍaśī (also known as Mahā Tripurāsundarī, Lalitā, or Rājā Rājeśvarī), but she is also closely identified with all of the Mahavidyas, as is revealed in these mantras. Thus her traditions are diverse, expansive, mysterious, and unique in the world of Tantra.
Sarasvati Puja is the day that celebrates the Mother of knowledge, learning, music, the arts, and language. Sarasvati (or Saraswati) is literally “she who continuously flows,” and as Vak is the the divine voice that created the universe in the Rg Veda, the ultimate power of divine speech itself. Sarasvati was also a divine river of the Vedas that provided food, water, and sustenance. Her esoteric form is Matangi, the Mahavidya of inner knowledge and hidden wisdom. As the Mother of speech and language, she is the mother of all mantras, as she created language as a vehicle for divine power.
