Answer

Yes, you can do Navkarsi the next day even if you did not do Choviyar the previous night.

Explanation

In Jain practice:

• Choviyar means not eating after sunset.
• Navkarsi means not eating or drinking until a specific time after sunrise, traditionally after completing the Navkarsi time period.

These are related to discipline in food habits, but one does not automatically depend on the other. If you could not observe Choviyar one night, you may still observe Navkarsi the next morning with proper intention and discipline.

Spiritual Understanding

Jain Dharma encourages gradual self-control, awareness, and reduction of attachment to food and taste. If one practice was missed, it is better to continue with the next good practice rather than feel discouraged.

Takeaway

Yes, do Navkarsi with sincerity. Missing Choviyar does not stop you from observing Navkarsi the next day.
