Short answer We avoid vegetables in Paryushan to practice ahimsa (non‑violence), self‑control, and simplicity at the highest level, when countless small lives thrive in the rainy season. Eating fewer and simpler items helps us reduce harm and focus on pratikraman, samayik, and forgiveness.

A little more detail

• Ahimsa: Root vegetables (potato, onion, garlic, carrot, beet, etc.) are avoided because uprooting them kills the whole plant and disturbs many tiny lives in the soil. Leafy/green vegetables often carry more small organisms during monsoon.
• Fewer new lives: Fresh greens, sprouts, and fermented foods are avoided as they increase or harbor many microorganisms.
• Samyama and tapas: Limiting variety, taste, and quantity reduces attachment and passions, supporting vows, pratikraman, and meditation.
• Seasonal care: During Chaturmas (monsoon months that include Paryushan/Das‑Lakshan), restraint is increased because unseen life is abundant.

Practice by tradition

• Shwetambar: Commonly avoid all root vegetables; many also avoid all green/fresh vegetables during the 8 days, taking mainly grains, pulses, and simple preparations. Some keep fasts or take only boiled water in daylight.
• Digambar (Das‑Lakshan): Similar spirit of restraint; root and green vegetables are avoided, with strong emphasis on limited, simple meals and various fasts.

What this looks like in the kitchen

• Avoid: root vegetables; green/leafy vegetables; sprouts; fermented foods; eating after sunset.
• Prefer: simple grains and pulses, minimal spices, daylight meals; or fasting as per one’s vows.
