A great overview of the science of purifying the self in a wonderfully spiritual setting of Yosemite National Park. Through four sessions at a California weekend retreat, Mokhtar Maghraoui inspires the audience to be self-reflective and to assess the state of their nafs (inner self) in the context of completing the journey back to Paradise. The completion of this journey is largely dependent on the type of nafs we possess: the cattle-like nafs, the predator-like nafs, the satanic-like nafs or the angelic-like nafs. How do we determine which one we possess and how do we elevate our nafs to a state that is pleasing to our Creator? In analyzing these states of the soul, the imam also prescribes practical ways to guard against its debasement by both Shaitan and our lower desires. And finally, the example of the purified soul, that of our beloved Prophet Muhammad (P), is discussed in an effort to make the lessons of this series more relevant to our daily lives. (Duration: 4 hours, 22 min) Imam Mokhtar received his Islamic education in Algeria before coming to the U.S. He has served as an imam in New York and is a Central Shura Member of ICNA and a member of the Scholars Council of North America. He is a former member of the Fiqh Council of North America and is an active participant in interfaith dialogues.
