I think you’re asking about Jain practices related to food and meal times. Here is a simple, true-to-dharma overview:

• Core principle: Food should be non-violent (ahimsa) and pure in intention. Jains often prefer vegetarian food and avoid harm to living beings in food preparation.
• Common dietary features:

- Many lay Jains avoid root vegetables (like onions, garlic, potatoes) because uprooting plants harms many organisms. - Eggs are avoided; meat and fish are not consumed. - Milk and dairy are accepted in most traditions, but some individual practitioners may choose stricter limits.

• Meal timing and fasting:

- There isn’t a single universal “mealtime rule” for all Jains. Daily routines vary by family and region. - Fasting (upavasa) is a prominent practice in Jainism, practiced on many auspicious days or during the holy month of Paryushan/Dash Lakshan, as well as on personal vow days (vratas). Fasting ranges from partial fasting (restricting certain foods or meals) to complete fasting, and the rules differ between Digambar and Śvetāmbara traditions. - Some households observe lighter meals earlier in the day and allow a larger, balanced lunch; other households may have only one meal a day during certain vratas.

• Digambar vs. Śvetāmbara differences:

- There are variances in how strictly certain foods are avoided and in the specific rules for fasting, meals, and rituals. In general, both traditions emphasize ahimsa, purity of intention, and disciplined eating, but the exact practices can differ.

If you were asking about a specific aspect (e.g., which foods are traditionally avoided, or how fasting days are observed), tell me exactly which part you want explained and I’ll give you a precise, tradition-aware explanation.
