Not a particular experience in my case, rather a gradual series of events. My parents were Christian but their religion seemed wrong for me, and the more I experienced of Christian culture the less I liked it. After reading The Bible as a young adult I concluded that (a) I was fortunate to have survived with mind and character somewhat intact and (b) all religion was rubbish. The latter was a mistake of course, based on assuming that it was all like what I had grown up with. Later, after half a lifetime of reading including the Gita, Patanjali, and a lot else and some other experience, I began to realize that some religious traditions were fundamentally positive. This boggled me at first as it seemed too good to be true, however it is partially confirmed as I have learned a little more. Edit: Belatedly realized the title is a little off. I don't want to be too pedantic, but Hinduism as I understand it is not really faith-based, in the sense of having to affirm some irrational dogmas. Using "faith" as a synonym for religion effectively includes Abrahamist religion and excludes the rest. It can be just a verbal habit on the part of people from Western background so it may not represent what the OP really meant, and my post was based on this liberal interpretation.
Hinduism and hindu peoples never force anyone to become hindu...if anyone by himself or herself wants to accept hinduism than it's okk.
