spirituality defined

there are more things in heaven and earth than are ever dreamt of in your philosophy, Horrie [Hamlet's advice to a materialist mate after chatting with his dad's ghost]

I've come up with a neat definition of spirituality for the spiritually inclined, which I think captures much of the yearning, the confusion and the consolation.
To be spiritual is to believe that there is more to this world than this world, and to know that by believing this you're a better person than those who don't believe it.
