I took a 3 credit hour course on comparative religions and i am sharing the slides that my class made for presentations.You can download them from below mentioned link. However, these slides are of very basic level. If you need resources for in depth study ,I would suggest you to contact someone who is currently studying at a university where this course is being taught.(E.g Kinnaird College)
