I don't really understand what the word spiritual means.
I'm not religious, for starters. I don't pretend to know much, and try to work out a lot (and usually fail). I get overwhelmed by my own ignorance sometimes, especially that I do not know how ignorant I truly am. The reasonable possibilities seem to be, that I either know essentially nothing about this existence, or a tiny, but sort of notable fraction. And anywhere between of course. I tend to favour the first option rather heavily, but for no rational reason. It is anathema to me, to form an opinion out ignorance, and to pretend to know something I don't (which doesn't mean I don't spend as much time doing it as the next person, but may mean I have more fever in destroying such an opinion, should I realise its foundation).
I meditate daily, but for the benefits to focus and attention, and because the unrealistic feats meditaters tend to perform in fiction (and the odd real one) I've been exposed to, have left me with a bias towards it as a lifestyle practice. I deliberately treat the more esoteric reasons for meditation with scepticism. I've yet to have any of the more eccentric experiences some claim can happen through meditation.
I do however, have what appears to be an objective morality. Whilst I struggle to follow it (or rather, the little I understand of it), it keeps me firmly anchored even in the most depressing of mindsets. It makes Nihilism and Materialism seem absurd, which I think are typically opposites to the term spirituality.
I don't know where this leaves me on the spiritual scale. I resent science being proposed as a non-spiritual thing (it's just a truth finding method, not a foundation for a belief system), but won't make much fuss about it beyond that.
