Answer

In Atma Siddhi Shastra, the stanza that begins with:

“Ātmā dravya nitye chhe…”

is traditionally counted as Gāthā 63.

Explanation

This gāthā is part of Shrimad Rajchandraji’s explanation of the nature of the soul. The opening words mean:

“The soul, as a substance, is eternal.”

It expresses the Jain principle that the soul is a real, eternal substance, though its states or modes change.

Takeaway

This stanza teaches the Jain view that the ātma is eternal in its substance, while its conditions change due to karma and spiritual development.
