I may be walking on shaking ground here, but...
Neeraj/ Ebisu-san, how are you so sure about God's plans? I think there is a line that goes somehow like this: "His will works in mysterious ways."
And.. There may not be always good intentions behind our "fate", "destiny", "whatever".
Because there is no good without evil. There is no darkness without light.
I'm not saying we should give up. But.. Is it right, that something causes us sorrow, and we do it, only in order to cause others happiness?
