The Power of Concentration Is a Purifying Force

The power of concentration is that it suppresses the defilements at a particular time. But as soon as you're out of the concentration, then these unwholesome states just re emerge. This relates to another point i've made in other contexts, that it's often pointed out that buddhism can give rise to the same kinds of pathologies as islam. I have more experience of tibetan buddhism, but in so far as i no zen as well.
