Answer

Yes, after doing Tivihar, you may eat the next morning, but in Jain practice you should eat only after completing the proper morning rule, commonly including Navkarsi if you have taken that vow or follow that discipline.

Explanation

Tivihar generally means renouncing three types of intake after sunset/night:

• Food
• Water
• Mukhvas or similar consumables

The next morning, the night-time restriction ends after sunrise, but many Jains observe Navkarsi, which means eating only after a prescribed period after sunrise.

If you have specifically taken Navkarsi pachchakkhan, then you should not eat before completing Navkarsi time.

If you did only Tivihar and did not take Navkarsi, then strictly speaking Tivihar itself does not automatically mean you must do Navkarsi. However, many Jain families and traditions commonly connect morning eating with Navkarsi discipline.

Spiritual Understanding

In Jain Dharma, vows and restraints should be followed according to the exact pachchakkhan taken. The important point is sincerity and clarity:

• If you took Navkarsi, observe it.
• If you did not take Navkarsi, do not falsely claim that you observed it.
• When unsure, ask your guru, sadhu-sadhviji, or knowledgeable elder according to your tradition.

Takeaway

After Tivihar, eating next morning without Navkarsi depends on whether you took Navkarsi pachchakkhan. If you took it, wait. If not, Tivihar alone does not necessarily require Navkarsi.
