Sāṅkhya Yoga · Verse 24
"अच्छेद्योऽयमदाह्योऽयमक्लेद्योऽशोष्य एव च | नित्यः सर्वगतः स्थाणुरचलोऽयं सनातनः"
"acchedyo 'yam adāhyo 'yam akledyo 'śoṣya eva ca | nityaḥ sarva-gataḥ sthāṇur acalo 'yaṃ sanātanaḥ"
This is uncuttable, unburnable, unwettable, undryable. It is eternal, all-pervading, stable, immovable, ancient
The four negative attributes from the previous verse transform into positives: acchedyaḥ (uncuttable), adāhyaḥ (unburnable), akledyaḥ (unwettable), aśoṣyaḥ (undryable). The prefix a- denotes absolute impossibility.
Then five positive attributes: nityaḥ (eternal), sarvagataḥ (gone to all places, omnipresent), sthāṇuḥ (post, pillar, stable), acalaḥ (without movement), sanātanaḥ (perpetual, from always).
Sarvagataḥ is crucial: the ātman is not confined to an individual body. It is omnipresent like space, but conscious.
