Yakshadevasuri Maharaj Saheb is a revered Śvetāmbara Jain monk in the Upkeśa Gaccha lineage. He is traditionally listed as the direct successor of Acharya Ratnaprabhasuri, and was consecrated as an acharya after serving as upadhyaya (principal teacher). In the usual biographical tradition, Ratnaprabhasuri (the founder of the Oswal lineage) consecrated Yakshadevasuri as the next head of the order, and Yakshadevasuri went on to guide the monastic community and its four notable disciples who founded later sub-gacchas.

Key points in simple terms:

• Role: Acharya (head preceptor) in the Upkeśa Gaccha Śvetāmbara Jain tradition.
• Lineage: Son-like successor of Ratnaprabhasuri, the sixth in that line; continued the monastic lineage and its organizational branches.
• Significance: Known for continuing the spiritual guidance of the Upkeśa Gaccha and for the expansion of its monastic network.

Note on traditions:

• This attribution and sequence come from Śvetāmbara Pattavalis (biographical chronicles) and are part of the Upkeśa Gaccha narrative.
• Jain historiography can differ between Śvetāmbara and Digambara traditions in naming and dating early ascetics, so exact dates and lists may vary by tradition.

If you’d like, I can summarise what the traditional Pattavalis say about Yakshadevasuri in more detail, or explain how he fits into the broader Upkeśa Gaccha history.
