Verse 329

असंख्येयोऽप्रमेयात्मा विशिष्टः शिष्टकृच्छुचिः ।सिद्धार्थः सिद्धसंकल्पः सिद्धिदः सिद्धिसाधनः ॥ ४० ॥

In plain words

Beyond counting. A Self no measure reaches. He stands apart from everything else that is. He does good to the good and He gives the commandments. He is clean through and through. Every purpose of His is already accomplished; whatever He resolves is done in the resolving. He gives the attainment — and He is the way to it.

Close to the Sanskrit

Uncountable; whose Self is immeasurable; distinguished above all; doer of good to the good; pure; whose every purpose stands accomplished; whose every resolve is fulfilled; the giver of attainment; the means of attainment.
