“A human being in perfection ought always to preserve a calm and peaceful mind and never to allow passion or a transitory desire to disturb his tranquility.”

“A human being in perfection ought always to preserve a calm and peaceful mind and never to allow passion or a transitory desire to disturb his tranquility. I do not think that the pursuit of knowledge is an exception to this rule. If the study to which you apply yourself has a tendency to weaken your affections and to destroy your taste for those simple pleasures in which no alloy can possibly mix, then that study is certainly unlawful, that is to say, not befitting the human mind. If this rule were always observed; if no man allowed any pursuit whatsoever to interfere with the tranquillity of his domestic affections, Greece had not been enslaved, Caesar would have spared his country, America would have been discovered more gradually, and the empires of Mexico and Peru had not been destroyed.”

“Simplicity has no name is free of desires. Being free of desires it is tranquil. And the world will be at peace of it's own accord.”

“Real love brings about calm—not inner torment. True love allows you to be at peace with yourself and with God. That is why Allah says: “that you may dwell in tranquility.” Hawa is the opposite. Hawa will make you miserable. And just like a drug, you will crave it always, but never be satisfied. You will chase it to your own detriment, but never reach it.”

“It is in your power to withdraw yourself whenever you desire. Perfect tranquility within consists in the good ordering of the mind, the realm of your own.”

“The more tranquil a man becomes, the greater is his success, his influence, his power for good. Calmness of mind is one of the beautiful jewels of wisdom.”
