as for the yellow it becomes fire the black becomes dust the blood becomes air and the phlegm becomes water. this is the resurrection of the body. as for the spiritual which is the perceptive rational soul of man if it is purified by perseverance in worship and is cleansed by avoiding whims and desires and is nourished by the nourishment of the sciences and knowledge received from the guiding imams it will unite upon leaving the body with the spiritual world from which it separated and it will be happy by returning to its original homeland. for this reason it is called a return so it was said {return to your lord wellpleased and pleasing} and this is paradise. and to him the symbol fell in the story of adam and his being in paradise then his separation from it and his descent to the lower world then his return to it in the afterlife. and they claimed that the perfection of the soul is with its death for with it is its deliverance from the narrowness of the body and the physical world just as the sperm is in the deliverance from the darkness of the womb and the exit to the open space of the world and the human being is like the sperm and the world is like the womb and knowledge is like food. so if it penetrates into it it becomes truly complete and is delivered. so if it is prepared for the abundance of spiritual knowledge by acquiring knowledge from the imams and following its beneficial paths with their guidance it is completed upon leaving. the body and what was not apparent appeared to her and for this reason he peace be upon him said people are asleep and when they die they wake up and the more the soul is distant from the world of the senses the more it is prepared for spiritual sciences. likewise if the senses are stagnant through sleep they look at the world of the unseen and sense what will appear in the future either with its eyes so it does not need an interpreter or with an example so it needs an interpretation. so sleep is the brother of death and in it appears the knowledge of what was not in wakefulness. so likewise death reveals matters that did not occur to the heart of a human being in life. this is for souls that have been sanctified by practical and scientific exercise. as for the souls that are upside down and immersed in the world of nature
أما الصفراء فتصير نارا وتصير السوداء ترابا ويصير الدم هواء ويصير البلغم ماء وذلك هو معاد الجسد وأما الروحاني وهو النفس المدركة العاقلة من الانسان فانها ان صفيت بالمواظبة على العبادات وزكيت بمجانبة الهوى والشهوات وغذيت بغذاء العلوم والمعارف المتلقاة من الأئمة الهداة اتحدت عند مفارقة الجسم بالعالم الروحاني الذي منه انفصالها وتسعد بالعود الى وطنها الأصلي ولذلك سمي رجوعا فقيل {ارجعي إلى ربك راضية مرضية} وهي الجنة وإليه وقع الرمز بقصة آدم وكونه في الجنة ثم انفصاله عنها ونزوله الى العالم السفلاني ثم عوده اليها بالاخرة وزعموا ان كمال النفس بموتها إذ به خلاصها من ضيق الجسد والعالم الجسماني كما أن النطفة في الخلاص من ظلمات الرحم والخروج الى فضاء العالم والانسان كالنطفة والعالم كالرحم والمعرفة كالغذاء فإذا نفذت فيه صارت بالحقيقة كاملة وتخلصت فإذا استعدت لفيض العلوم الروحانية باكتساب العلوم من الأئمة وسلوك طرقها المفيدة بإرشادهم استكملت عند مفارقة الجسد وظهر لها ما لم يظهر ولذلك قال عليه السلام الناس نيام فإذا ماتوا انتبهوا وكلما ازدادت النفس عن عالم الحسيات بعدا ازدادت للعلوم الروحانية استعدادا وكذلك إذا ركدت الحواس بالنوم اطلعت على عالم الغيب واستشعرت ما سيظهر في المستقبل إما بعينه فيغنى عن المعبر او بمثال فيحتاج الى التعبير فالنوم اخو الموت وفيه يظهر علم ما لم يكن في اليقظة فكذا الموت تنكشف امور لم تخطر على قلب بشر في الحياة وهذا للنفوس التي قدستها الرياضة العملية والعلمية فأما النفوس المنكوسة المغمورة في عالم الطبيعة
