Answer

In Jain Dharma, masturbation is generally understood as connected with kāma-vikār and lack of control over the senses, so it is spiritually harmful. For repentance, there is no single fixed number of kāyotsarga or Navkar Mantra that applies to everyone.

A simple and respectful practice can be:

• Do 1 kāyotsarga with sincere repentance.
• Recite the Navkar Mantra 9 times, slowly and with awareness.
• Make a firm but humble resolve: “I will try to control my thoughts and senses better.”

Explanation

In Jainism, the most important thing is not only the number, but the feeling of pratikraman, repentance, and self-control.

You may say in your heart:

• “Micchāmi Dukkaḍaṁ” with sincerity.
• Ask forgiveness for the wrong thought and action.
• Resolve to avoid triggers and improve gradually.

If you follow a particular Jain tradition or have a guru, it is best to ask them for the exact penance, because rules of prāyaścitta can vary according to tradition and personal discipline.

Spiritual Understanding

The aim of Jain Dharma is not to create guilt, but to awaken awareness. Mistakes should lead to:

• Repentance
• Self-restraint
• Better control over mind, speech, and body
• Progress toward brahmacharya

Takeaway

Do 1 kāyotsarga and 9 Navkar Mantras with sincere repentance, and focus on improving your self-control. If possible, take guidance from a trusted Jain guru or elder.
