This looks like a (slightly distorted) form of a Jain bīja–mantra connected with “Om Hrim Shree Arham…”, which is used in some traditions as a subtle mantra of Arihant Paramatma.

However, written exactly as:

> Om hrim sri arham a si aa hu sa

it does not clearly match a standard, scripturally‑fixed Jain sūtra or widely accepted mantra form from main Digambar or Shwetambar traditions. It seems either:

• Misheard / misremembered syllables, or
• A localized or guru‑given mantra with slight phonetic changes.

Because of that, I cannot confidently give you an exact word‑by‑word meaning from authentic scriptures without risking inaccuracy, which goes against the principle of preserving Jain Dharma in a pure way.

If you can provide:

• The script version (Devanagari or Gujarati), or
• The name of the stotra / sūtra or the Jain text / guru you received it from,

then it may be possible to identify the correct, traditional form and its proper arth (meaning). As it stands, in this exact syllable sequence, it is not a clearly recognized classical Jain sūtra.
