Cattāri Brahmavihārā

Another reason for the Buddha’s reluctance to try to impose his ideas of justice on others was his perception that the effort to seek justice as an absolute end would run counter to the main goal of his teachings: the ending of suffering and the attainment of a true and blameless happiness. He never tried to prevent rulers from imposing justice in their kingdoms, but he also never used the Dhamma to justify a theory of justice. And he never used the teaching on past kamma to justify the mistreatment of the weak or disadvantaged: Regardless of whatever their past kamma may have been, if you mistreat them, the kamma of mistreatment becomes yours. Just because people are currently weak and poor doesn’t mean that their kamma requires them to stay weak and poor. There’s no way of knowing, from the outside, what other kammic potentials are waiting to sprout from their past.
