श्लोक 2.20

न जायते म्रियते वा कदाचिन्नायं भूत्वा भविता वा न भूयः। अजो नित्यः शाश्वतोऽयं पुराणो न हन्यते हन्यमाने शरीरे॥

na jāyate mriyate vā kadācin nāyaṁ bhūtvā bhavitā vā na bhūyaḥ, ajo nityaḥ śāśvato 'yaṁ purāṇo na hanyate hanyamāne śarīre.

Meaning

The real you is the soul, not the body. Your body may change, but your soul lives forever. So there is no need to be afraid.
