Ghiyas al-Din Mansur ibn sadr al-Din Dashtaki shirazi (alived in 866-948 A.H) was one of the prominent philosopher in shiraz.
He had special talent in knowing philosophical and traditional sciences.
He has left various works which some of them are about the critique of Jalal al-Din Davanis views (dead in 907) and the response of Davani's critics which has expressed on his father's views, Sadr al-Din Dashtaki.
The present works, Ishraq Hayakil al-Nur, is a description on one of the Shahab al-Din Suhrevardi's most important works (549-587 A.H) called Hayakil al-Nur Dashtaki has written this description during 7days in autumn at the age of 18 against Jalal al-Din Davani's description called Shavakil al-Gharur. Though most often Dashtaki's views seem to be true, but his abusive prose intends reader to accept Dabani's views.
