Forgiveness doesn't mean forget what happened. If something is serious and it is necessary to take counter-measures, you have to take counter-measures.
Dalai LamaWe should reflect on the idea that since the beginning of time sentient beings have been mentally unstable because they have been slaves of delusion, they lack the eye of wisdom to see the path leading to nirvana and enlightenment, and they lack the necessary guidance of a spiritual teacher. Moment by moment they are indulging in negative actions, which will eventually bring about their downfall.
Dalai LamaIf we have a positive mental attitude, then even when surrounded by hostility, we shall not lack inner peace.
Dalai Lama
