|Canto 11: General History||Chapter 5: Nārada Concludes His Teachings to Vasudeva|
Bhaktivedanta VedaBase: Śrīmad Bhāgavatam 11.5.17
eta ātma-hano 'śāntā
sīdanty akṛta-kṛtyā vai
ete — these; ātma-hanaḥ — killers of the self; aśāntāḥ — devoid of peace; ajñāne — in ignorance; jñāna-māninaḥ — presuming to have knowledge; sīdanti — they suffer; akṛta — failing to perform; kṛtyāḥ — their duty; vai — indeed; kāla — by time; dhvasta — destroyed; manaḥ-rathāḥ — their fanciful desires.
The killers of the soul are never peaceful, because they consider that human intelligence is ultimately meant for expanding material life. Thus neglecting their real, spiritual duties, they are always in distress. They are filled with great hopes and dreams, but unfortunately these are always destroyed by the inevitable march of time.
There is a similar verse in Śrī Īśopaniṣad (3):
asuryā nāma te lokā
tāḿs te pretyābhigacchanti
ye ke cātma-hano janāḥ
"The killer of the soul, whoever he may be, must enter into the planets known as the worlds of the faithless, full of darkness and ignorance."
