Das Lakṣaṇa Parva (the 10-day festival) is a Digambar Jain observance focused on strict self-control and fasting, but the exact practice can vary by person and guru. Here’s the common Jain approach in simple terms:

• Eating plans (three levels of restraint):

- Low restraint: eat normally but avoid restricted items. - Moderate restraint: eat one meal a day (ekāśana) or limit to two light meals. - High restraint: upavās (fasting all day) or even complete fasting on certain days (often the first and last days).

• Typical dietary rules during these days:

- Eat before sunset. - Do not eat root vegetables (onion, garlic, potato, carrot, radish, etc.). Do not consume fermented foods or foods that are heavily processed. Do not eat very spicy or heavy foods; keep meals simple and sattvic. Boiled water is commonly preferred if drinking water during fasting; in stricter observances, some drink only boiled water or refrain from intake of any food.

• How the days are usually kept:

- Some people choose ekāśana or two light meals each day. - Others may take upvas (fruit-based fasting) or a very light diet with limited items. - On many communities, the first and the last days are kept as stricter fasts, sometimes with only boiled water.

• Important note for accuracy:

- The exact rules are not universal. Digambar households and temples may follow different gradations (extreme, average, low) and may differ in which foods are avoided or allowed. The core aim is to cultivate restraint, ahimsa (non-violence), and self-purification, not hardship for its own sake.

• Practical tips:

- Decide your level of fasting in consultation with your guru or community guidelines. - Plan meals that stay away from root vegetables and heavy spices, eaten before sunset. - If you cannot fast fully, aim for at least one lighter meal or a day of upvas, and gradually build from there in future years.
