Hi everyone,
Starting from a premise that life is accidental and a product of random gene variations and NS....religions will be seen as human constructs born out of fear and human imagination. In this situation, the subject of comparative religions will only be a matter of preparing a multi column chart with various religions and their respective teachings listed down side by side....to be committed to memory.
No one can make any sense of it all except perhaps in the respective social, political and cultural contexts.
On the other hand, if life is seen as a spiritual journey then the first requirement is to understand spirituality, its philosophy and its mechanisms....common to all humans and to all life. Once this is done, understanding religions is a cakewalk. All teachings from the Upanishads, to the Gita to Moses to Buddha to Jesus to Mohammad...and even modern day teachings can all be understood very clearly in a common context relevant to specific social & cultural differences. Everything will fall into place.
Cheers.
Sriram
