It is very hard to change the ways of evil people. They are swayed by the power of their senses and succumb to them. The six evils of desire, pride, greed, anger, infatuation and jealousy constantly plague such people. These evil tendencies are our enemies and iit is these enemies who destroy our life. Jealousy is a cancer and anger is a demon. In fact, demons are not separate species. Rather people with evil qualities are indeed demons. Demonic tendencies cling tightly to us and it is very difficult to get rid of them. As the body has many parts, the mind, too, has its own parts which assume perverse forms. The mind outlives the body and finds a habitation in the human body in the next life. Hence, it is necessary to direct the mind toward Nivritti and not toward Pravritti. That alone will help.  (SSB 1996, p. 68)
