In Jain tradition, a guru or monk who is addressed as “Guru Maharaj” typically observes the five Mahavratas (great vows) as the core ascetic vows. These are:

• non-violence (ahimsa)
• truth (satya)
• non-stealing (asteya)
• celibacy (brahmacharya)
• non-attachment/non-possession (aparigraha)

Both Digambar and Shwetambar communities uphold these five vows for monks, though there are some ritual and practice differences between the two traditions. If you have a specific Guru Maharaj in mind (a particular monk or lineage), I can share details about that individual’s vows as they are observed in that tradition.
