I look for ever more simple definitions of the term “spiritual”.

Yet another perfectly mundane way of defining the word would be to say that the spiritual is all the stuff that’s about keeping spirits up.

In a way that is what the religious stories, myths and beliefs were there to do: provide a kind of antidote to the troubles of life made all the more acute by heightened awareness. Simply, to keep the spirits up.

Can the antidote be dispensed with in favour of a commitment to the bald facts of life? I don’t know. Pure existentialism is a tough call.
