Here is a simple 8-day Jain fasting plan (upavas) that is commonly followed during Das Lakshana or similarly observed periods. It focuses on simple, ahimsa-oriented meals and mindful discipline. You can adapt it to fit Digambar or Shwetambar practices as needed.

Core principles to follow during the 8 days

• One meal a day (ekasana) or two light meals only if you prefer two meals. Many follow ekasana throughout.
• No root vegetables (mool—onion, garlic, potatoes, carrots, roots in general), and no meat, fish, eggs, or harm to living beings.
• No grains that you avoid on fast days in your community; if you normally avoid grains, continue that. If you’re unsure, keep the meals very simple (fruit, dairy, lentils without whole grains, and easily digestible items).
• Vegetarian dairy is allowed if you consume dairy; otherwise use plant-based substitutes.
• Abstain from strong spices, fried foods, and heavy oils; keep salt minimal.
• Focus on mindfulness, self-discipline, and positive conduct (samayik, pranayama, and ahiṃsā in action).

Day-by-day plan (example structure) Day 1

• Morning: Warm water or herbal tea (if your tradition allows) or just water.
• Main meal (after sunrise or early afternoon): A light, single meal consisting of any combination of:

- Fresh fruit (e.g., apples, pears, mangoes when in season) or a fruit smoothie made with water or plant milk. - A small portion of dal (lentil) or legume-based dish without heavy grains, prepared with minimal spices. - A small serving of non-root vegetables (like leafy greens) cooked lightly with salt and a little oil.

• Evening: If following ekasana, no additional food. Otherwise a small fruit or a bowl of curd/yogurt (if dairy is allowed).

Day 2–Day 7 (repeat with variety)

• Morning: Warm water; optionally a light fruit or a small glass of fresh juice.
• Main meal: A single, simple plate such as:

- Steamed or lightly sautéed vegetables with a pinch of salt and turmeric. - A smaller portion of dal or boiled lentils; avoid heavy gravies. - Fresh fruit or a fruit salad for dessert. - If dairy is allowed, a small serving of yogurt or milk once during the day.

• Optional minor snack (only if your tradition allows and you’re sure you won’t break the fast): a handful of soaked almonds or peanuts (without salt). Avoid heavy fried snacks.
• Evening: If not following two meals, no additional food. If following two meals, keep the second meal very light (fruit or dairy-based item).

Day 8 (concluding day)

• Transition meal: A bit more food than the previous days but still light and simple. You can have:

- A small bowl of dal with steamed greens and a chapati made from flour you typically avoid on fast days (only if you follow a grain-based vrat; otherwise skip grains and keep it fruit/dal/greens). - Plenty of water throughout the day.

• Reflection: End with a short mental vow to continue non-violence and simple living, and resume normal meals gradually afterward.

Practical tips

• Hydration: Drink water steadily throughout the day; you can include warm water or herbal tea if permitted.
• Portions: Keep portions deliberately small to honor the fasting spirit and avoid heavy digestion.
• Flexibility: If you feel faint or unwell, listen to your body. It’s better to adjust the plan than to push beyond your limits. The aim is purification and restraint, not hardship.
• Conduct: Pair the diet with a day of quiet reflection, minimal speaking, and, if possible, a short period of samayik or pranayama.

If you want, tell me:

• Whether you follow Digambar or Shwetambar practice (to tailor the plan more precisely),
• Whether you prefer ekasana (one meal a day) or two lighter meals,
• Any dietary restrictions ( dairy allowed or not, allergies, etc.).

I can then customize the 8-day plan to fit your exact tradition and needs.
