In Jain Dharma, a sadhu observes perfect brahmacharya and complete restraint of the senses.

• Bodily changes may happen due to karma and body nature, but a true sadhu does not indulge in desire.
• The focus is always on vigilance, detachment, and self-control.
• Any such bodily state is treated as a natural physical condition, not as something to be enjoyed or encouraged.
• The monk continues in samayik, dhyan, swadhyay, and restraint, maintaining inner purity.

In Jain view, the main ideal is: to conquer desire, not to follow it.

If a person is speaking about a specific conduct-rule of Jain monks, the exact practice can differ slightly between Digambar and Shwetambar traditions.
