Answer

In Jainism, fasting is a very important form of tapasya — spiritual discipline. It is practiced to reduce attachment to the body, control desires, purify karma, and strengthen self-restraint.

Some common Jain fasts include:

• Upvas – Complete fasting for one day, usually without food. Many people take only boiled water during permitted hours.
• Chauvihar Upvas – A stricter fast in which one avoids both food and water after sunset, and in some cases for the full fasting period.
• Tivihar Upvas – Fasting from food, but boiled water may be taken during the allowed daytime period.
• Ayambil – Eating only one simple meal in the day, without taste-enhancing items such as oil, ghee, milk, curd, sweets, spices, fruits, or green vegetables.
• Ekasana – Eating only once in one sitting during the day.
• Beasana / Biyasana – Eating only two times in the day, with discipline and limits.
• Navkarsi – Taking food or water only after a set time after sunrise, traditionally after doing Navkar Mantra remembrance.
• Porsi – Eating only after one-fourth of the day has passed.
• Sadh-Porsi – Eating only after one and a half porsi has passed.
• Purimuddh – Eating only after half the day has passed.
• Avaddh – Eating only after three-fourths of the day has passed.
• Chauvihar – Avoiding all food and water after sunset until the next day.
• Tivihar – Avoiding food after sunset, while water may be allowed according to tradition and vow.
• Attham – Fasting for three continuous days.
• Atthai – Fasting for eight continuous days.
• Masakshaman – Fasting continuously for about one month.
• Varsitap – A long tapasya traditionally connected with Bhagwan Rishabhdev, often observed by fasting on alternate days for about one year.
• Oli / Navpad Oli – A nine-day period of Ayambil, observed twice a year, with devotion to the Navpad.
• Santhara / Sallekhana – A very advanced spiritual vow of gradually giving up food and attachment near the end of life, undertaken with equanimity and guidance.

Explanation

Jain fasting is not merely about not eating. Its deeper purpose is to practice:

• Self-control over taste, hunger, and comfort
• Ahimsa by reducing consumption
• Karma nirjara — shedding of accumulated karma
• Awareness of the soul as separate from the body
• Equanimity in discomfort

There are also differences in practice among Jain traditions, families, and individual vows. For example, rules about water, timing, and food items may vary according to one’s sect, guru guidance, health, and capacity.

Spiritual Understanding

In Jain Dharma, fasting becomes meaningful when it is done with:

• humility, not pride
• peaceful thoughts, not anger
• forgiveness and compassion
• scriptural reflection, prayer, and meditation
• detachment from taste and bodily comfort

A fast done with ego or show is not considered spiritually fruitful. A smaller vow done with pure feelings can be more valuable than a difficult fast done with pride.

Takeaway

Jain fasts range from simple daily disciplines like Navkarsi, Ekasana, Beasana, Tivihar, and Chauvihar to intense tapasya like Attham, Atthai, Masakshaman, Varsitap, and Sallekhana. The true aim is not bodily hardship, but purification of the soul through self-restraint, awareness, and detachment.
