Having discussed the reason for everything with mom , I can understand one thing , people who are continuously in the thought of Holy things , go fast. It happened with my grandfather , grand mother and my father. They had the same temparment,same trust in God , same spirit .People who think of Him more go there quickly. The funny thing is in the last moments my fathers hands were folded as if he had seen or reached a point of bliss.And some thing else happened.

So to the questions of 'why?' this is the answer. But am I satisfied with it ? No. Mind will go back to it and I will take days to reconcile from the thoughts.The meaning of personal loss cannot be defined.
