This wordly life is like a shadow. If you try to catch it, you will never be able to do so. If you turn your back towards it, it has no choice but to follow you.
Beware of every hour and how it passes, and only spend it in the best possible way, do not neglect yourself, but render it accustomed to the noblest and best of actions, and send to your grave that which will please you when you arrive to it.
Everything that is loved, if it is not loved for His sake then this love is nothing but distress and punishment. Every action that is not performed for His sake then it is wasted and severed. Every heart that does not reach Him is wretched; veiled from achieving its success and happiness.
