This paper engages with the literature of Jāmbhojī, the founder of the Biśnoī sampradāya. It examines the complex depiction of Nāths and Nāthism in Jāmbhojī’s Sabadavāṇī. The Sabadavāṇī harshly criticizes Nāthyogīs for their hypocritical or harmful religious practices. However, it incorporates yogic-tantric terminology and concepts, especially when referring to the state of sahaja (the mystical state of unity and liberation). Moreover, it includes several passages of the Gorakhabāṇī, which are portrayed as the original teaching of Jāmbhojī. This paper seeks to demonstrate that the critique of Nāths and the adoption and reinterpretation of yogic-tantric elements as teachings of Jāmbhojī can be viewed as a strategy of authorizing Jāmbhojī and his teaching. In this way Jāmbhojī is established as the true teacher and supreme yogi. The quest for establishing the spiritual authority of Jāmbhojī reflects early processes of forging a community of followers in the multifaceted religious landscape of early modern Rajasthan.
