“Ahaar Vigyaan” (आहार विज्ञान) in Jainism means “the science of food” – understanding food from a spiritual, ethical, and health point of view.

Here is a simple overview:

1. Meaning of Ahaar (Food) in Jainism

- Ahaar is not just what we eat; it is considered a main support of the body and also a big cause for karma-bandh (bondage of karma) if taken with violence, carelessness, or attachment. - So Jain Ahaar Vigyaan focuses on non-violence (ahimsa), sanyam (self-control), and saatvikta (purity) in food.

1. Main Principles of Ahaar Vigyaan (Jain View)

- Ahimsa in Food: - Avoid killing higher life-forms for food. Hence, strict Jains avoid meat, fish, eggs, honey, etc. - Minimize harm even to lower life forms (e.g., avoid root vegetables in many traditions because many tiny lives live in them and whole plant is destroyed). - Aparigraha (Non‑possessiveness) in Eating: - Eat simple, limited, non-luxurious food. - Avoid overeating and greed for taste. - Sanyam (Discipline): - Fixed times for eating (especially for monks and many disciplined laypeople). - No eating at night (for those who follow it) to avoid killing small insects and to reduce passions. - Shuddhi (Purity): - Food should be clean, fresh, prepared with right intention, without anger or hatred. - Avoid alcohol and intoxicants because they disturb the mind and increase passions (kashayas).

1. Types of Ahaar (from spiritual / karmic angle)

In Jain texts, sometimes food is looked at in various ways, for example: - Bhiksha / Gochar Ahaar: Food taken by monks from householders with rules. - Saatvik / Asaatvik: - Saatvik: Simple, pure, non-violent, easily digestible. - Asaatvik: Very spicy, fried, alcoholic, fermented, or that excites passions and laziness. - Food can support good meditation if pure, or disturb the mind if impure.

1. Difference in Traditions (General)

- Shvetambar and Digambar both follow the same basic principles: ahimsa, aparigraha, and sanyam in food. - Some detailed rules (what exactly to avoid, how many times to eat, etc.) can differ for muni / aryika / shravak depending on their tradition and specific texts or acharyas. - But the core of Ahaar Vigyaan – non-violence, purity, and control – is same in both.

1. Why Ahaar Vigyaan is important in Jain Dharma

- Body is needed for sadhana (spiritual practice). Right food keeps body fit and mind calm. - Wrong food increases kaam, krodh, maan, lobh (passions), which blocks right faith and right knowledge. - By purifying food, we slowly purify mind and conduct, helping in progress towards moksha.

If you tell me what exactly you want:

• Basics of Jain diet?
• Rules for shravak / shravika?
• Scientific (health) benefits of Jain food?
• Or any specific granth / sutra related to Ahaar?

I can explain that part of “Ahaar Vigyaan” in more detail.
