If you can wait and not be tired of waiting, or being lied about, don't deal in lies. Or being hated, don't give way to hating, and yet don't look too good, nor talk too wise.
Only those beneath me can envy or hate me. I have never been envied nor hated; I am above no one. Only those above me can praise or belittle me. I have never been praised nor belittled; I am below no one.
What you dislike in your superiors, avoid doing to your inferiors. What you dislike in your inferiors, avoid doing when working for your superiors. What you hate in those who are in front of you, do not do to those behind you.
One of the first signs of the beginning of understanding is the wish to die. This life appears unbearable, another unattainable. One is no longer ashamed of wanting to die; one asks to be moved from the old cell, which one hates, to a new one, which one willl only in time come to hate.

I agree with your remark about loving your enemy as far as actions are concerned. But for me the cognitive basis is the trust in an unrestricted causality. 'I cannot hate him, because he must do what he does.' That means for me more Spinoza than the prophets.
For the poison of hatred seated near the heart doubles the burden for the one who suffers the disease; he is burdened with his own sorrow, and groans on seeing another's happiness.
