Bhagavad Gita 2.24

अच्छेद्योऽयमदाह्योऽयमक्लेद्योऽशोष्य एव च।नित्यः सर्वगतः स्थाणुरचलोऽयं सनातनः॥

acchedyo'yamadāhyo'yamakledyo'śoṣya eva ca |nityaḥ sarvagataḥ sthāṇuracalo'yaṃ sanātanaḥ ||

This Self cannot be cut, burned, wetted, nor dried up; it is eternal, all-pervasive, stable, immovable, and ancient.

It is impenetrable; it cannot be drowned, scorched, or dried. It is eternal, all-pervasive, unchanging, immovable, and most ancient.

Our plain-language meaning of this verse is waiting for scholar review.
