Lord Krishna confirms that the demoniac nature is in itself a hellish condition of life perpetuating more and more degraded hellish existences. The three portals to hellish existence are lust, greed and anger which completely destroy and ruin all opportunities for advancing in spiritual consciousness. Lust, greed and anger are the foundations for all the other vices and sinfulness described previously which run rampant among the demoniac. The word dvaram means portal and gate inferring the cause. The words nasanam atmanah means destructive or even suicidal denoting how utterly negative lust, greed and anger are in evolving the consciousness to commune with the immortal soul. Therefore Lord Krishna emphasizes that lust, greed and anger must be permanently abandoned, fully relinquished and completely neutralised since these three voracious vices comprise the cause that leads a jiva or embodied being directly to dreaded naraka or the hellish planets.
