Answer

If you mean the Jain fasting/meal practice, Chauvihar comes before Navkarshi — that is, no food or water is taken after sunset until Navkarshi, which is usually observed 48 minutes after sunrise. ( jainqq.org)

Explanation

In simple terms:

• Chauvihar = abstaining from food and water after sunset.
• Navkarshi = taking food or water after sunrise, traditionally after 48 minutes. ( jainqq.org)

Spiritual Understanding

This practice supports self-restraint, discipline, and अहिंसा in daily Jain life. It helps one remain mindful of time, food, and vows. ( jainsamaj.org)

Takeaway

So, before Navkarshi is Chauvihar. ( jainqq.org)
