(worth profound deliberation)
A person who is deluded is wretched in this world, and is duped in the next world because he has sold what is better for what is baser.
Do not admire yourself.
Sometimes you may be deceived by your property and your bodily health into supposing that you will last forever.
Sometimes you are deceived by your long life, your children and your friends into thinking that you will be saved by them.
Sometimes you are deceived by your beauty and the circumstances of your birth, which bring you your hopes and desires so easily that you think that you are truthful and successful in achieving your goal.
Sometimes you are deceived by the regret you show people for your shortcoming in worship, but Allah knows the opposite of that is in your heart.
Sometimes you make yourself worship in a spirit of reluctance; but Allah desires sincerity.
Sometimes you imagine that you are calling on Allah when you are calling on another.
Sometimes you imagine that you are giving good counsel to people, while your real desire is that they bow to you.
Sometimes you blame yourself when you are really praising yourself.
Know that you will only emerge from the darkness of delusion and desire by sincerely turning in repentance to Almighty Allah, and to whatever you know about Him, and to recognize the faults in your self which are not consistent with your intellect and knowledge, and which the faith, the law and the customary practices of the Holy Prophet and the Imams of guidance do not tolerate.
If you are content with your present condition, there is no one more wretched than you in knowledge and action, nor anyone with a more wasted life.
You will inherit grief on the Day of Resurrection.
