Here is a simple, Jain-dharmic guide to fasting (upvas). Fasting is a common spiritual practice in Jainism to Purify the mind and body and to cultivate self-control.

What fasting means in Jainism

• Fasting is voluntary self-restraint from certain foods and sometimes from all food for a period.
• It is done with the aim of reducing violence to living beings (ahimsa), controlling passions, and increasing focus on spiritual practices like prayer, self-reflection, and penance (pratikraman).

General types of fast

• Upvas (fast day): You restrict what you eat and may skip meals. The exact rules vary by community and tradition.
• Ekadashi-style fasts: Monthly or occasion-specific fasts with stricter rules than a regular day.
• Nirjala fast (no water): A very strict fast observed by some during special occasions like Paryushan/Mahaparva; it allows neither food nor water for a period. This is intense and should be undertaken only with guidance and medical caution.

Common rules you’ll often see (vary by Digambar/Shwetambar practice)

• No root vegetables (to avoid harming small organisms and to reduce violence).
• For many fasts, grains and cereals are avoided; some allow fruits, dairy, or cooked legumes, depending on the tradition.
• No eating after sunset is common for many upvas; some allow a single meal at midday.
• Daily prayers, repentance (pratikraman), and meditation are often part of the fast day.

Practical steps to observe a fast

• Decide the type and duration of the fast (half-day, full day, or longer) based on your tradition and health.
• Plan the diet for the fast day (if allowed). Common options include:

- Light meals with allowed non-grain items (e.g., fruits, dairy, legumes, and certain prepared foods that fit your tradition). - No food at all (nirjala) only if you have the guidance and health clearance.

• Prepare spiritually: begin with a short prayer or meditation, perform pratikraman (confession and reflection on mistakes), and set a sincere intention for the fast.
• Hydration: If your tradition allows water, keep a steady intake of water or fluids; if you are doing nirjala, do not drink water—only undertake this if you are well-hydrated beforehand and have medical clearance.
• Break the fast mindfully: break with a simple, approved food and thankfulness for the opportunity to practice restraint.

Health and safety

• If you have health issues (diabetes, pregnancy, elderly, or any medical condition), consult a healthcare professional before undertaking a fast.
• It’s okay to start with shorter fasts and gradually increase, under guidance.

Tradition-specific notes

• Digambar: Fasts can be very strict, including long periods without food and sometimes no water (nirjala) on certain days, depending on the practitioner.
• Shwetambar: Fasts often allow more flexibility in what is eaten (e.g., milk/dairy may be permitted in some cases) and may emphasize dual practices like pratikraman along with abstinence.
