A class on Bhagavad Gita 2.23-24 given by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada on August 27, 1973 in London.
Bhagavad Gita 2.23
nainaṁ chindanti śastrāṇi
nainaṁ dahati pāvakaḥ
na cainaṁ kledayanty āpo
na śoṣayati mārutaḥ
The soul can never be cut to pieces by any weapon, nor burned by fire, nor moistened by water, nor withered by the wind.
Bhagavad gita 2.24
acchedyo ’yam adāhyo ’yam
akledyo ’śoṣya eva ca
nityaḥ sarva-gataḥ sthāṇur
acalo ’yaṁ sanātanaḥ
This individual soul is unbreakable and insoluble, and can be neither burned nor dried. He is everlasting, present everywhere, unchangeable, immovable and eternally the same.
