The authorship of the text is controversial. According to the Vedanta tradition, "Atmabodha" was written by Shankara for his pupil and disciple, Sanandana, in the 8th century; however, many scholars today doubt this authenticity. That said, the text does closely align with and advocate the teachings of Advaita Vedanta and its system.
The text is addressed to scholars who are peaceful in their hearts and who have freed themselves from cravings. It is intended to be read by those who desire liberation and have used austerities to purify themselves in their quest to find this. It is described as a treatise of the “Knowledge of the Self.”
Atmabodha is also the name of one of the Upanishads of the "Atharvaveda."
