Bhagavad Gita 2.30

देही नित्यमवध्योऽयं देहे सर्वस्य भारत।तस्मात्सर्वाणि भूतानि न त्वं शोचितुमर्हसि॥

dehī nityamavadhyo'yaṃ dehe sarvasya bhārata |tasmātsarvāṇi bhūtāni na tvaṃ śocitumarhasi ||

This indweller in the body of everyone is ever indestructible, O Arjuna; therefore, you should not grieve for any creature.

Do not be anxious about these armies; the spirit in man is imperishable.

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