त्रिविधं नरकस्येदं द्वारं नाशनमात्मनः। कामः क्रोधस्तथा लोभस्तस्मादेतत्त्रयं त्यजेत् ॥

tri-vidhaṁ narakasyedaṁ dvāraṁ nāśhanam ātmanaḥ kāmaḥ krodhas tathā lobhas tasmād etat trayaṁ tyajet

Triple is the gate of this hell, destructive of the self—lust, wrath, and greed; therefore let man renounce these three.

In plain words: Krishna says hell has three doors that destroy a person: lust, anger and greed. So everyone should give up these three.
