"And now, my children, I am about to die, and I tell it unto you in truth, if you take not heed against the spirit of lies and anger, and if ye love not truth and generosity, you will perish. The spirit of anger casts the net of error around its victim, and it blinds his eyes, and the spirit of lies warps his mind, and clouds his vision. Evil is anger, it is the grave of the soul. Desist from anger and hate lies, that the Lord may dwell among you, and Behar flee from your presence. Speak the truth each unto his neighbor, and you will not fall into anger and trouble, but you will be at peace, and the Lord of peace you will have with you, and no war will vanquish you.
