Bhagavad Gita 2.24
The self is uncuttable, unburnable, permanent, all-pervading and ancient.
अच्छेद्योऽयमदाह्योऽयमक्लेद्योऽशोष्य एव च।
नित्यः सर्वगतः स्थाणुरचलोऽयं सनातनः॥
acchedyo 'yam adāhyo 'yam akledyo 'śoṣya eva ca
nityaḥ sarvagataḥ sthāṇur acalo 'yaṃ sanātanaḥ
Translation
"It cannot be cut, burned, wetted or dried. It is permanent, present everywhere, fixed, unmoving and timeless."
Hindi
"यह काटा नहीं जा सकता, जलाया नहीं जा सकता, भिगोया नहीं जा सकता और सुखाया भी नहीं जा सकता। यह नित्य, सर्वव्यापी, स्थिर, अचल और सनातन है।"
Commentary
The previous verse said what cannot happen to the self. This one gives the positive terms: lasting, all-pervading, fixed and ancient. Ramanuja and Shankara read some of these words differently, since "all-pervading" can mean that the self enters all states or that it is one with the whole, but both agree it is beyond change. 2.25 turns this knowledge into a reason to stop grieving.
