"A quarrelsome bhikkhu shrouded by delusion, does not comprehend the Dhamma taught by the Awakened One when it is revealed. Annoying those practiced in meditation, being led by ignorance, he is not aware that his defiled path leads to Niraya-hell. Falling headlong, passing from womb to womb, from darkness to (greater) darkness, such a bhikkhu undergoes suffering hereafter for certain.
"As a cesspool filled over a number of years is difficult to clean, similarly, whoever is full of impurity is difficult to make pure. Whoever you know to be such, bhikkhus, bent on worldliness, having wrong desires, wrong thoughts, wrong behavior and resort, being completely united avoid him, sweep him out like dirt, remove him like rubbish. Winnow like chaff the non-recluses. Having ejected those of wrong desires, of wrong behavior and resort, be pure and mindful, dwelling with those who are pure. Being united and prudent you will make an end to suffering."
