You ask how it is possible to be your own father and son. You should seek answers, although it is better to anticipate some, to be the light and dream.
What people fear most about tragedy is its randomness - a taxi cab jumps the curb and hits a pedestrian, a gun misfires and kills a bystander. Better to have some rational cause and effect between incident and injury. And if cause and effect aren't possible, better that there at least be some reward for all the suffering.
I've always believed in God. I also think that's the sort of thing that either comes as part of the equipment, the capacity to believe, or at some point in your life, when you're in a position where you actually need help from a power greater than yourself, you simply make an agreement.
