“Maharaj Saheb” is a very respectful title used in Jainism for sadhus (monks), like:

• Acharya Shri … Maharaj Saheb
• Pujya … Vijayji / Sagarji / Muni ji Maharaj Saheb, etc.

“Mahabodhi Maharaj Saheb” seems to be a specific Jain sadhu you are asking about, but from your short message it is not clear which guru or which sangh/sect you mean. Many monks are known locally by such names, and details (location, sangh, lineage) can differ.

To help you properly, please write a little more detail, for example:

• From which city or state?
• Digambar, Shwetambar Murti-pujak, Sthanakwasi, Terapanthi, etc.?
• Any known disciple, sangh, or organization name?

General meaning of “Maharaj Saheb” in Jainism (for clarity):

• It is an honorific, showing deep respect for a monk.
• It is not always a formal post like “Acharya”.
• Both Digambar and Shwetambar Jains commonly say “Maharaj Saheb” to senior monks. ( jainknowledge.com)
