In an age in which religion is not commonly held to be good or necessary, it's probably wise to think for a bit why it has generally been thought to be necessary. It wasn't entirely an imposition. (Pace Westphalia.)
I think you have to do one of two things. Either try with your heart, soul and mind to see the real truth, past the commonly held notions, or in the event, especially when the event involves others, to deal as honestly as you can. (This is, of course, a reflection of another duality.)
If you don't do at least one of those two things, the odds are you're probably going around doing things as a part of something that you wouldn't want to be a part of if you understood what it might be.
