त्रिविधं नरकस्येदं द्वारं नाशनमात्मनः । कामः क्रोधस्तथा लोभस्तस्मादेतत्त्रयं त्यजेत् ॥२१॥
tri-vidhaḿ narakasyedaḿ dvāraḿ nāśanam ātmanaḥ kāmaḥ krodhas tathā lobhas tasmād etat trayaḿ tyajet
tri-vidham — of three kinds; narakasya — of hell; idam — this; dvāram — gate; nāśanam — destructive; ātmanaḥ — of the self; kāmaḥ — lust; krodhaḥ — anger; tathā — as well as; lobhaḥ — greed; tasmāt — therefore; etat — these; trayam — three; tyajet — one must give up.
There are three gates leading to the hell of self-destruction for the soul—lust, anger, and greed. Therefore, all should abandon these three.
The beginning of demoniac life is described herein. One tries to satisfy his lust, and when he cannot, anger and greed arise. A sane man who does not want to glide down to the species of demoniac life must try to give up these three enemies, which can kill the self to such an extent that there will be no possibility of liberation from this material entanglement.
