Answer

This story is not something I can confirm as a universally accepted, canonical Digambar Jain scriptural story.

It may be a popular devotional or oral story told in some places to explain the power of the Navkar Mantra, but I should not present it as established fact without a clear scriptural source.

Explanation

In Jain tradition, the Navkar Mantra is considered extremely holy and powerful. Many stories in Jain culture describe:

• the spiritual strength of chanting the mantra,
• peaceful remembrance at the time of death,
• and the soul’s upliftment through pure faith.

But not every story told in the community is part of the main, commonly accepted scriptural tradition. Some are local, devotional, or symbolic narrations.

So for the specific story you mentioned:

• the exact event may be a folk/devotional story,
• but I cannot verify it as a standard Digambar Jain scriptural fact.

Spiritual Understanding

The real Jain teaching is that pure devotion, right faith, and remembrance of the sacred mantra are spiritually beneficial. The emphasis is not on sensational details, but on:

• faith,
• purity of mind,
• and detachment from fear even in suffering.

If a story inspires श्रद्धा toward the Navkar Mantra, it may have devotional value, but it should still be understood carefully and respectfully.

Takeaway

So, in short: I cannot confirm that snake story as an authentic canonical Digambar Jain fact. It may be a traditional devotional story, but not necessarily a verified scriptural incident.
