This is the crux of the moral pessimists: if they really wanted to promote their neighbor's redemption, then they would have to resolve themselves to spoiling existence for him, and thus to being his misfortune; out of pity, they would have to--become evil!
The mind of one who practises doesn't run away anywhere, it stays right there. Good, evil, happiness and unhappiness, right and wrong arise, and he knows them all. The meditator simply knows them, they don't enter his mind. That is, he has no clinging. He is simply the experiencer.
Can it be That modesty may more betray our sense Than woman's lightness? Having waste ground enough, Shall we desire to raze the sanctuary And pitch our evils there?
