Abstract

Naser Khosaw's didactical Mathnawi, "Rushanai Name" is one of the oldest Persian didactic verses, in which he has introduced his ethical doctrine the same as he had previously declared in his prose works "Zad-ol-Mosaferin" and the "Djame-ol- Hekmatain". The author believes that this ethical doctrine is derived from three main sources, i.e. the Islamic ethic, the philosophical ethics and the pre Islamic Iranian ethics of Sasanian. The Mathnawi is assumed to be structurally divided into three sections: philosophical paradigms as a whole, in nine sections, the ethical method of philosophy in six sections, the advices of the Zarathustra clergy(moubad) in six sections and the Ending in four sections. The ethic and didactic doctrine is presented in three main axes: The recognition of the soul and the three types of the soul, and recognizing the virtues and vices and the way to purgative soul.
