'Righteous hatred' is in the same category as 'righteous cancer' or 'righteous tuberculosis'. All of them are absurd concepts.
Tibetan Buddhism from the Ground up, Wisdom (1993)
The point of Buddhist meditation is not to stop thinking, for ... cultivation of insight clearly requires intelligent use of thought and discrimination. What needs to be stopped is conceptualisation that is compulsive, mechanical and unintelligent, that is, activity that is always fatiguing, usually pointless, and at times seriously harmful.Alan Wallace
