In Jainism, "Sadhu ni Mata" refers to the guidelines, rules, or conduct (Mata means "opinion", "view", or "prescription") that Jain sadhus (monks) and sadhvis (nuns) must follow in their daily lives. These rules are based on the core principles of Jainism such as Ahimsa (non-violence), Satya (truth), Asteya (non-stealing), Brahmacharya (celibacy), and Aparigraha (non-possession).

Some key aspects of Sadhu ni Mata include:

1. Ahimsa: Sadhus must avoid harming any living being, not just in action but also in thought and speech.
2. Non-attachment: They renounce all worldly possessions and relationships, practicing total detachment.
3. Limited Food and Water: They accept food and water only from specific sources, after sunrise and before sunset, and only what is necessary for survival.
4. Truthfulness: Sadhus must always speak the truth and avoid any form of falsehood or exaggeration.
5. Chaturmas: During the monsoon, sadhus stay in one place to avoid harming small organisms that proliferate during rains.
6. No Use of Vehicles: They travel only on foot to avoid harming living beings.
7. Aparigraha: They own only a few essential items, such as a bowl, a broom (Ogho or Rajoharan), and religious scriptures.
8. Daily Practices: They perform rituals like Pratikraman (reflection and repentance), Swadhyaya (study of scriptures), and meditation.

These rules ensure that Jain monks and nuns live a life of extreme discipline, minimizing harm to other living beings and progressing on the path to liberation (moksha).
