Answer

Yes, you can do Navkarsi even if you did not do Chauvihar the previous night.

Explanation

Chauvihar means not taking any food or water after sunset.

Navkarsi means eating or drinking only after about 48 minutes after sunrise, after remembering Navkar Mantra or doing proper religious reflection.

So, if you could not observe Chauvihar at night, you may still observe Navkarsi in the morning by waiting until the Navkarsi time.

Spiritual Understanding

In Jain Dharma, every small restraint is spiritually valuable. If one vow or practice could not be followed, it does not mean another good practice should be skipped.

Doing Navkarsi helps develop:

• self-control,
• awareness before eating,
• respect for discipline,
• and purification of daily conduct.

Takeaway

Not doing Chauvihar does not stop you from doing Navkarsi. Do Navkarsi with sincerity and try to gradually strengthen your discipline.
