Shri Gurucharitra Adhyay 39. Shri Gurucharitra, the central scripture of the Datta sampradaya, written by Saraswati Gangadhar in the fifteenth century. It tells the lives of Shripad Shrivallabha and Shri Nrisimha Saraswati, the first two incarnations of Dattatreya, as a dialogue between Siddha and Namdharak. Traditionally read as a saptaha — the whole book over seven days — most often in the month of Margashirsha. This adhyay is named in its colophon for वृद्धवंध्यासंतानप्राप्ति.
