In Jain scriptures, there is no fixed numerical rule like:

> “After reciting 1 Navkar Mantra, X number of pāp (sins/karmas) are reduced.”

What the Agams and traditional acharyas clearly say is:

• Navkar Mantra is “savva‑pavappanāsano” – it destroys all sins (i.e., it becomes a very strong cause for pāpa‑karma nirjarā and for stopping new pāp).
• The amount of pāp reduced depends on:

- your bhāv (inner feelings – shraddhā, vinay, shuddha bhāvnā), - your upayog (how focused you are), - freedom from raag–dvesh at that time, - and your past karmic load.

So:

• If someone asks, “Exactly how many pāp go away with one Navkar?”

→ The correct Jain answer is: “It cannot be counted in numbers; it depends on one’s purity of mind and karmas.”

However, Jain ācāryas and kathakārs sometimes use illustrative statements like:

• “One letter of Navkar destroys sins of many sāgaropam years,”
• “One full Navkar destroys immense pāp,” etc.

These are meant to show its greatness, not to give a literal mathematical count.

So, in simple words:

• Yes, one Navkar, recited with true devotion and concentration, does reduce pāp‑karma.
• No, Jain śāstra does not give a fixed number of pāp for “one Navkar.”
