Please let me know all Jain fast

In Jainism, fasting (upavāsa or tapasyā) is an important spiritual practice, observed as a means of self-purification, penance, and control over desires. There are various types and methods of fasting, ranging from partial to complete abstinence from food and/or water. Here are the main types of fasts practiced in Jainism:

1. Paryushana Fast (Paryushan Parva)

• The most significant period of fasting, observed annually for 8 days (Swetambara) or 10 days (Digambara).
• Devotees undertake various austerities, including complete fasts and other forms.

2. Ayambil

• Only one meal is taken in the day, consisting of food without any taste enhancers like salt, sugar, oil, ghee, milk, curd, or raw fruits/vegetables.

3. Ekashana

• Eating only once during the day, without any food or water before or after that meal.

4. Biyasana

• Having two meals in a day, with restrictions similar to Ekashana.

5. Upavasa (Complete Fast)

• Total abstinence from all food and sometimes even water, usually for 24 hours (from sunrise to next sunrise).

6. Chauvihar Upavasa

• No food or water is taken from sunset until after sunrise the next day.

7. Tivihar Upavasa

• No food is taken for 24 hours, but water is allowed until sunset.

8. Varsitap

• Alternating days of fasting and eating, sometimes performed for 13 months and 13 days, representing Lord Rishabhanatha's austerity.

9. Navkarsi

• The first meal is taken at least 48 minutes after sunrise.

10. Proshadhopavasa

• Fasting observed on the 8th and 14th days (Ashtami and Chaturdashi) of each lunar fortnight, often with meditation and scriptural study.

11. Santhara / Sallekhana

• A vow of voluntary, gradual fasting unto death, undertaken at the end of life as an act of spiritual purification and renunciation.

12. Other Minor Fasts

• Attham: Fasting for three days continuously.
• Atthai: Fasting for eight days continuously.
• Masakshaman: Fasting for one month.
• Chhath: Fasting for six days.

Purpose of Fasting in Jainism

Fasting is not just abstaining from food but is observed with an attitude of detachment, prayer, repentance, and self-discipline. It is meant to reduce passions (kashayas), destroy karmas, and help in spiritual upliftment.

Notes

• The duration, rules, and rigor of fasting can vary based on personal ability, guidance from spiritual teachers, and sectarian traditions (Shwetambaras, Digambaras, etc.).
• Fasting should always be accompanied by spiritual practices like meditation, scriptural study, and reflection.
