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

na jāyate mriyate vā kadāchin nāyaṁ bhūtvā bhavitā vā na bhūyaḥ ajo nityaḥ śhāśhvato ’yaṁ purāṇo na hanyate hanyamāne śharīre

He is not born, nor doth he die; nor having been, ceaseth he any more to be; unborn, perpetual, eternal and ancient, he is not slain when the body is slaughtered.

In plain words: The soul is never born and never dies. It has always been and will always be, and it is not killed when the body is killed.
