Fasting (upvas) is a common Jain practice for self-purification and to reduce violence to living beings. Here is a simple, practical way to start, focused for lay followers.

What fasting means in Jainism

• It is a vrata (discipline) done with intention of non-violence, restraint, and inner purification.
• You can observe it in different degrees, from partial fasting to complete fast, depending on your capacity and guidance from your guru or tradition (Digambar or Śvetambar).

Ways you can start

• Ekvas (one meal a day): Eat only one light, plain meal during the day (usually noon). No eating before sunrise or after sunset if you choose.
• Partial fasting (upvas with restrictions): Eat only allowed foods (often simple, non-stimulating foods like fruits, dairy, cooked vegetables, and cereals) and avoid roots, coarse spices, or heavy fried items.
• Full/longer fast: Abstain from all food for a day or more, often with non-meat, non-eggs, and mindful drinking water if you follow a less strict form. Some communities practice water-only fasts (nirjala) on specific days, but this is advanced and should be done with guidance.

Before you begin

• Decide the type and duration (e.g., one day, or a few hours, or a full day) and inform someone you trust.
• Choose a clean, quiet day; many lay followers observe fasting on auspicious days or during specific holy periods.
• Plan simple, non-violent food if you’re doing a partial fast (e.g., fruits, dairy, cooked vegetables, lentils in modest amounts).
• Prepare mentally: set a clear intention (samkalpa) to reduce harm, cultivate self-control, and improve inner peace.

Practical guidelines for the day

• Start with a light, pure intention and recite a short vow if you practice doing so.
• If you are having your one meal, keep it simple and nutritious; avoid heavy or fried foods.
• Stay hydrated unless you are doing an explicit waterless fast; sip water as needed and avoid overeating at the single meal.
• During the fast, you may engage in gentle activities like walking, meditation, or studying Jain philosophy to keep your mind steady.
• Break the fast gently with a small, easy-to-digest item if you’re doing a one-meal-fast, otherwise you’ll resume normal eating after the designated period.

What to watch for

• If you feel faint, dizzy, or unwell, end the fast safely and seek rest and nourishment. Fasting should not endanger health.
• If you have health conditions or are pregnant, consult a trusted Jain teacher or elder before starting a fast.

Differences to note

• Digambar and Śvetambar communities have slightly different traditions around fasting practices and permissible foods. Your local guidance from a knowledgeable guru or elder in your tradition is best for specifics.
