Professor Ansarian:
A sick heart changes the stomach into a usurper, a stomach is nothing on its own.
Imam Sadeq (A.S) says: our heart is a warehouse for organs and limbs, the consumption of our organs and limbs is from this warehouse and they are nothing on their own.
This is an accurate psychoanalysis and psychology. Now, if someone,s heart is sick and he is zealous to treat it, he must act according to the prescription of the Allah Almighty which is the Holy Quran, he must act based on the traditions and theculture of Ahl al-Bayt (AS) since they are the treatment for All pains.
