The six enemies of man are eating into his vitals, embedded in his own inner consciousness. They are the demons to be killed. They are lust (kama), anger (krodha), greed (lobha), attachment (moha), pride (mada) and malice (matsarya). They reduce man to the level of a demon. (SSS Vol.9)
A wave of service, if it sweeps over the land, catching everyone in its enthusiasm, will be able to wipe off the mounds of hatred, malice and greed that infest the world. (SSS Vol.28)
