Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
There are three gates leading to this hell – lust, anger and greed. Every sane man should give these up, for they lead to the degradation of the soul.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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.
