Diksha (renunciation) is followed by the practice of Chaturmas—the four-month monsoon period—where a Jain monk observes intensified austerities, travels less, and teaches/studies in one or a few places to avoid harming living beings during rains. For Mahavir Swami, the post‑Diksha period is described in Jain texts as him engaging in deep penance and teaching during the rainy season, a hallmark of the Chaturmas practice.

Key points

• What it is: Dixa (diksha) ends a household life; Chaturmas is the four-month rainy-season observance that follows, emphasizing restraint, meditation, and teaching.
• Purpose: To uphold ahimsa (non‑violence) and spiritual progress during a time when life in the countryside is abundant but fragile (monsoon).
• Traditions: There are differences in emphasis between Digambar and Shwetambar traditions on exact practices and locations, but both affirm the four-month monsoon observance after Diksha.
• After Mahavir’s Diksha, texts describe him continuing austere practices and imparting spiritual teachings during Chaturmas, though the precise places and details can vary across sources.
