The Buddha said that wisdom can come only from the abandonment of selfish craving, or desire. One who abandons that desire attains Nirvana, which means supreme peace and liberation. In Sanskrit, Nirvana means to blow out, to exhale the breath. Its opposite, desire, is to breathe in. Now, if you breathe in and hold it, you lose your breath; but if you breathe out it comes back to you. So the point is: If you want life, do not cling to it, let it go.

-Alan Watts

They say that progress illuminates the darkness. But there will always be darkness. And in that darkness there will always be Evil, in that darkness there will always be fangs and claws, murder and blood. There will always be things that go bump in the night. And we, witchers, are the ones who bump back at them.

-Vesemir of Kaer Morhen
