Professor Reza Aslan crisscrossed the globe for his new spiritual adventure CNN series "Believer," where he immersed himself in religious traditions both familiar and downright bizarre -- to know "better than to take the truth claims of any religion (including my own) too seriously". I saw the first episode where he covered Hinduism, esp. a new sect (if we can call it as such) - the Aghoris - that rejects the caste system within Hinduism and don't consider anything to be bad, including eating human flesh, drinking urine.
It is a great show and I recommend his program to anyone interested in learning about world religions. More can be found by clicking here and here.
