Do you think the truest path to self realization, salvation, is your religion and no other religion?
If your answer to both the above are yes, a couple more simple questions -
(a) Were you born into your religion?
(b) Did you make a conscious choice of religion after considering all alternatives?
If the answer to the above is (a), then what really was the basis for the first contention that your religion is the best? Is it not as childish as a kindergarten kid claiming that his shoes are the best?
