According to Buddhist psychology, most of our troubles are due to our passionate desire for and attachment to things that we misapprehend as enduring entities. The pursuit of the objects of our desire and attachment involves the use of aggression and competitiveness as supposedly efficacious instruments. These mental processes easily translate into actions, breeding belligerence as an obvious effect.
Such processes have been going on in the human mind since time immemorial, but their execution has become more effective under modern conditions. What can we do to control and regulate these 'poisons' - delusion, greed, and aggression? For it is these poisons that are behind almost every trouble in the world.
