Religion is not a tangible entity. It in itself does not have the power guide a man's actions. A man's actions right or wrong are by his own choice. A choice he makes independently. Even when he is coerced or influenced by some Godman or preacher or priest or an atheist, it's his independent choice to believe in such sermons that influences his actions. A book when read will have a million things, some to be done some not to be done. A book will not do those things from you nor will it stop you from doing them. It's man's thought that guides him.
