A Study of the Relationship between Soul and Body from Nasir al-Din Al-Tusi's Point of View with a Glance at its Influence on Ethical Training of Human

Studying Nasir al-Din Al-Tusi's point of view about the relationship between soul and body and its influence on ethical training of human is important because he believes that soul and body are contrasted, and the relation between the soul and body is accidental; not substantial. Here in this research paper the authors studied the subject upon a descriptive and analytic method. Nassir al-Din Al-Tusi admits that there is some reciprocating influence of the body on resaving ethical virtues and of the soul on controlling body's faculties. He believes that the influence of soul on body happens through something named "Rohe Bokhari". "Rohe Bokhari" comes from a mixture of four-fold humours in the body. This mixture is the main Source of animalism and truculence of human. He believes that there are two kinds of virtues; one is natural and the other is adventitious. He acknowledges that the manner in which the four humors come to be mixture identifies the kind of virtues within "Rohe Bokhari" through which the basis of obtaining virtues would be prepared. It should be noted that there are several stages for ethical training of human. In the first stage the control on natural morality would be obtained through temperance of the temperament the four humors. In the second stage the soul must pay attention to the purpose and significance of the ethical training. Because the soul would be actualized through whatever it pays attention to. The third stage is the application of the will to control body's faculties. It would be obtained through imagination, recognizing the benefits, creating a strong passion, and the control of soul on the body's faculties. The Fourth stage is the repetition and practice in the acquisition of virtues and vices leave.
