Remember death, and be not angry, that your peace be not of constraint. As long as your life remains to you, cleanse your soul from wrath; for if it should go to Sheol with you, your road will be straight to Gehenna. Keep not anger in your heart; hold not fury in your soul; you have not power over your soul, save to do that which is good.
