The following study contains a translation of al-Bīrūnī's rendering into Arabic of the third chapter of Patañjali's Yogasūtra cum commentrary. (On this point see our translation of al-Bīrūnī's rendering of the first two chapters of Patanñjali's Yogasktra ). This translation is based on Ritter's edition of the Arabic text. Comparison has been made with the unique MS of Ritter's Text: KöprÜlÜ, 1589, fols. 412a–419a (writen on the margins). We have also compared the text with paralled passages and expressions in al-Bīrūnī's India.
