Acharya is the title given to the supreme spiritual leader or head of a Jain monastic order. The names you mentioned—Rajendra Suri (Acharya Rajendra Suri) and Yatindra Vijayji Maharaj Saheb—are well-known monastic figures in Jainism, but exact details about them (such as their sect, lineage, and current activities) depend on the particular Digambara or Śvetāmbara lineage they belong to.

Key points to understand about these titles and figures:

• Acharya: the head priest or supreme preceptor of a Jain order; responsible for guiding the monks/nuns, temple activities, and doctrinal matters within that lineage.
• Maharaj Saheb (or Maharaj): a respectful form used for senior or highly revered monks; not every senior monk is titled “Acharya.”
• Digambara vs. Śvetāmbara: Jain monastic lineages split into these two main traditions, each with its own line of acharyas, texts, and practices. The meaning and role of titles can differ between these traditions.
• Verification: to know precisely which lineage each name belongs to, one would check official temple or sangh (monastic community) communications, or trusted Jain knowledge resources that list current chaityas, acharyas, and their yajnas, sthanak or derasar affiliations.

If you’d like, I can share:

• The general duties and responsibilities of an Acharya in Jainism.
• How to identify the specific sect and lineage of a given Acharya.
• Jain prayers or stotras typically recited by senior monastics, with authentic Bharati/Artha (meaning) in line with Jain tradition.

Note: I can tailor the information to the Digambara or Śvetāmbara tradition if you specify which lineage you are referring to.
