The "Tripura-rahasya (The Secret of [the Goddess] Tripura)" is believed to be an abbreviated version of the original "Datta Samhita" or "Dakshinamurti Samhita" traditionally ascribed to Dattatreya. This more lengthy work was summarized by Dattatreya's disciple Parasurama, whose disciple, Sumedha Haritayana, scribed the text. Thus, this text is sometimes referred to as the "Haritayana Samhita".
