Which Side of the Tallit is Which?

With H-shem's help, we have begun learning Hilchot Tzitzit with the Ben Ish Chai, Hacham Yosef Hayyim of Baghdad. The sefer is translated by Shmuel Hiley and published by Yeshivath Ahavath Shalom Publications in Jerusalem 5765/2005. He calls the names of the Chapters by the names of Parashiot, so instead of Chapter One, the first chapter is called Parashath Bereshith, Laws of Ziziyoth. Please note these are for learning purposes only.  For the halacha lemaaseh, i.e. for what to do yourself please ask your own Rav.

8. There is no need to make any sort of sign on the tallith gadhol to indicate which side should be worn on the head, as some people do, as it is clearly stated in the teachings of the Ari z'l that it makes no difference at all which side of the tallith is on the head.

This learning should be in memory of Maran, HaRav HaGaon Ovadia Yosef, ztz'l.
