Answer

Yes, generally Navkarshi pachchakhān should be taken before eating or drinking, and it is best to take it after the Navkarshi time is completed.

If the Navkarshi time has already completed, you may still take pachchakhān after that, before you break the fast.

Explanation

In Jain practice, Navkarshi means not eating or drinking for a fixed period after sunrise. Traditionally, it is approximately 48 minutes after sunrise.

The usual method is:

• Wait until the Navkarshi time is over.
• After that, take pachchakhān properly.
• Then eat or drink.

If you forgot to take pachchakhān exactly at the time, but you have not eaten or drunk yet, then you can take pachchakhān after the time has completed and then do pāraṇā.

Spiritual Understanding

Pachchakhān is a conscious vow of restraint. It helps us practice awareness, discipline, and control over food intake. The main point is to maintain sincerity and avoid carelessness.

Takeaway

For Navkarshi:

• Complete the Navkarshi time first.
• Take pachchakhān before eating or drinking.
• If time has passed, you can still take pachchakhān before pāraṇā.

For exact local custom, it is best to follow guidance from your Guru Bhagwant, Sadhviji, or Jain sangh, because pachchakhān wording and timing may vary by tradition.
