Freedom with proper "Self" and universal responsibility and some common-sense in keeping one's focus into life affirmative values is enough religion for all. You will notice that only mediocre and confused people talk all the time about God. Which is basically an escapist idea and hiding their own incompetency. That is why you see all developed countries in the world are 'secular' to keep these religious people on the fringes, and excel in life, sports & work.
