Dattatreya
The Tripura-rahasya is divided into three parts. The first part, the Mahatmya Khanda or section on the goddess is concerned with the origin, mantra and yantra of the Goddess Tripura, also known as Lalita or Lalita Tripurasundari. The Jnana Khanda or section on knowledge elaborates on the themes of consciousness, manifestation, and liberation. The last part, Charya Khanda or section on conduct, has been lost and some believe destroyed.
