Answer

In Jain practice, Tivihar Pachchakhkhan means taking a vow to avoid three kinds of consumables—Ashan, Khaadim, and Swadim—for the rest of the day and the entire night, while water is still allowed. ( jainfoundation.in)

Explanation

The three categories are commonly explained like this: ( jainqq.org)

• Ashan — solid food such as grains and cooked meals. ( jainqq.org)
• Khaadim — items that are chewed or nibbled, such as fruits, dry fruits, and roasted grains. ( jainqq.org)
• Swadim — items like mouth fresheners and some medicinal or taste-related items, depending on tradition. ( jainqq.org)

In this context, Paan refers to drinks or water, and it is not included in Tivihar. That is why Tivihar is considered different from Chauvihar, where water is also avoided. ( jainqq.org)

Spiritual Understanding

Tivihar is a practice of restraint, self-discipline, and awareness. It helps a Jain devotee reduce attachment to food and strengthens the vow of संयम, while still keeping the observance practical for daily life. ( jainfoundation.in)

Takeaway

So, in simple words: Tivihar = giving up Ashan, Khaadim, and Swadim, while water remains allowed. If you want, I can also explain Chauvihar vs Tivihar in a very simple side-by-side way.
