An excerpt from "The Noble Eightfold Path" by Bhikkhu Bodhi

When such pursuits become widespread, the result is suffering, the tremendous suffering of individuals, social groups, and nations out to gain wealth, position, and power without regard for consequences. The cause for the endless competition, conflict, injustice, and oppression does not lie outside the mind. These are all just manifestations of intentions, outcroppings of thoughts driven by greed, by hatred, by delusion.
