Incalculables
How do you calculate, luck, karma, divine intervention and coincidence?
If you believe in God, you believe in divine intervention.
If your Buddhist you believe in Karma.
As for luck is that a term for those of no faith? "Man I was so lucky!"
Is luck in winning the lottery, even though its literally impossible for you to win, however someone wins, how do you explain these things.
When something is actually a true coincidence, very hard to explain.
