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.
