I would love to hear why you made your choice for Buddhism, to get some perspective.
Why did you choose Buddhism?
Why do you think it is the right path?
Well,because it makes sense for one.The Middle Way is pretty reasonable,you don't hear religious teachers telling people not to go to the extremes,and certainly not in 500 B.C.Second,it teaches that man is capable of reaching Nirvana without having to worship and pray to God,gods,etc.
On to your second question,yes I do think it is the right path.However,I don't think only Buddhist can reach Nirvana.Anyone who is kind,has right views,helps other people,etc. can find enlightenment and become a Buddha regardless of his religious views.
