antavanta ime dehā nityasyoktāḥ śharīriṇaḥ
anāśhino ’prameyasya tasmād yudhyasva bhārata|| 18||
ya enaṁ vetti hantāraṁ yaśh chainaṁ manyate hatam
ubhau tau na vijānīto nāyaṁ hanti na hanyate|| 19||
na jāyate mriyate vā kadāchin
nāyaṁ bhūtvā bhavitā vā na bhūyaḥ
ajo nityaḥ śhāśhvato ’yaṁ purāṇo
na hanyate hanyamāne śharīre|| 20||
vedāvināśhinaṁ nityaṁ ya enam ajam avyayam
kathaṁ sa puruṣhaḥ pārtha kaṁ ghātayati hanti kam|| 21||

My Understanding : Conscience and senses are like windows that shift with the direction of the wind. It is essential to steer our minds toward good and positive thoughts, regardless of external influences. The soul is eternal; it neither takes birth nor faces death.
