Answer

At night while sleeping, a Jain should ideally keep the mind peaceful and pure by remembering:

• Navkar Mantra
• Forgiveness prayer such as “Micchāmi Dukkaḍaṁ”
• Thoughts of Arihant, Siddha, Sadhu, and Dharma

The simplest and most recommended practice is to mentally recite the Navkar Mantra until sleep comes.

Explanation

Before sleeping, you can think:

• “I forgive all living beings.”
• “May all living beings forgive me.”
• “I have no hatred toward anyone.”
• “Namo Arihantāṇam, Namo Siddhāṇam…”

If you know the full Navkar Mantra, recite it slowly in your mind with devotion and awareness.

If you do not remember anything else, simply repeat:

“Namo Arihantāṇam”

or

“Micchāmi Dukkaḍaṁ”

with humility.

Spiritual Understanding

In Jain Dharma, the thoughts at night are important because sleep should begin with:

• forgiveness,
• non-violence in thought,
• detachment from anger and worry,
• remembrance of the pure souls.

Sleeping with the Navkar Mantra helps calm the mind and turns the final thoughts of the day toward purity and liberation.

Takeaway

Before sleeping, mentally recite Navkar Mantra and keep the feeling of forgiveness toward all living beings. This is a simple and spiritually beneficial Jain practice.
