..god..!!..??....do i need god..

what is god...sometimes i feel i should do something to find out more on this....n why do we need him so much..esp in all those times of hopelessness..despair....anger....?rather more in times of need and helplessness....what is it that really takes us there...may b not in a temple lk amitabh bachchan saying...khush to bahot hoge aaj types..but den from where does this concept of god has come?...per jisne bhi banaya bahot khoob banaya.....emotional catharsis ke liye to best hai....n out of that pouring people find the strength to fight back and head straight into the shining sun....going against the crashing waves and rising high....
