\n A man whose \u2018Aql\u2019 (intelligence) is supported by the \u2018Noor\u2019 (the insight) becomes knowledgeable, retainer, clever, insightful, and thoughtful. He should also \u2018\u0639\u0631\u0641\u2019 (Arif) recognise the real situation that he is in, the source of his situation, the reason beyond his existence, and the fate that he will inevitably encounter, through the sincere belief of Allah -azwj s oneness and the submission to the obedience (to Him -azwj ).

\n The \u2018\u0627\u0644\u0646\u0641\u0633\u2019 may (experience) the heat or coldness (through the Ruh). When heat (of Ruh) overcomes the coldness, he will behave in an evil and arrogant manner, feel comfortable, kill, rob, feel pleasant and dashing, commits sins and fornication, and spend lavishly. \n When the \u2018Ruh\u2019 covers that man with its coldness, he feels depressed, sad, submissive, withered, and oblivious. These are the symptoms that cause diseases.

\n This coldness is originates only when the individuals commit a sin and have a drink or food in an hour that is not appropriate to that drink or food-all in the same time; therefore, this will create a certain pain. \n Imam Jafar-e-Sadiq -asws explained the topic in other words: Man drinks, eats, and works through the fire; hears and smells through the wind; enjoys the taste of food and drink through the water; moves through the Ruh.

Food and drink cannot be digested in the interior body without the existence of the fire (acid) in the stomach. \n Without the existence of the wind, the fire of the stomach cannot be flamed (smell, sound, sight and taste all increase the stomach acid secretion) and the dregs cannot find an exit out of the abdomen. Without the existence of the Ruh, man cannot come and go; i.e., move. Without the existence of the cold water (in the stomach), the fire of the stomach would burn (a man).

Without the existence of Noor, man can neither see nor understand. \n The Clay (from which he was made) is his nature. The role of bones in the human body is similar to the role of trees on the surface of the earth. The hair on the skin plays the same role as of the grass on the earth. The nerves of the human body plays the same role of the bark on trees. The blood of the human body plays a similar role to that of water on the earth. The earth cannot endure without water.

Similarly, the human body cannot endure without the blood. The brain is the fat and the foam of blood.
