नैनं छिन्दन्ति शस्त्राणि नैनं दहति पावकः।
न चैनं क्लेदयन्त्यापो न शोषयति मारुतः।।2.23।।
2.23 Weapons do not cut It, fire does not burn It, water does not moisten It, and air does not dry It.
2.23 - 2.24 Weapons, fire, water and air are incapable of cleaving, burning, wetting and drying the self; for, the nature of the self is to pervade all elements; It is present everywhere; for, It is subtler than all the elements; It is not capable of being pervaded by them; and cleaving, burning, wetting and drying are actions which can take place only by pervading a substance. Therefore the self is eternal. It is stable, immovable and primeval. The meaning is that It is unchanging, unshakable and ancient.
