Listen, the crest is a symbol of purpose, a role that is beyond
your personal self, in this context, your spirituality grows to
embody a bigger cause, a bigger picture. This means that the "dirty
thing" has to deal with a bigger karma if it deals with you there
and then. Usually, they will shy away and wait for another
opportunity when you are, well, just yourself.
But make no mistake, carrying or displaying the crest without
believing in what it embodies is fruitless. It just makes it easier
for you mortals to relate to because you dont think about saving
the world 24/7, right?
