Is this the thing scientists call 'mass'?
Seriously, on the question of what spirituality means, here's one interpretation:
Spirituality comes from the Latin 'spiritus', meaning 'breath', which is intimately connected to life in that people die very quickly if they stop breathing, and is used as a metaphor for life in Latin and sometimes in English. So I suppose you could say that spirituality concerns itself with the essence of life. Eg: What does it mean to be alive? Does life have a purpose? Is it possible to divide life into separate entities, or are all life-forms aspects of a united whole?
Now you could say that religion attempts to answer many questions which people consider fundamental to the nature of life (such as what is meant by death) and as such it is spiritual. The same goes for much of secular science and philosophy as well. Unfortunately, 'spiritual' is nowadays taken to mean something intuitive, unscientific and/or concerned with divinity, but there's no need to load such connontations on it.
Then there's the idea of a spiritual experience. This could mean an experience which relates to spirituality in any way at all, such as a discussion of it, but normally what is meant is an experience which has a profound effect on a person's spirituality, ie their perception of the nature of life. This could induce euphoria, contentment or terror depending on how the person's beliefs change, but none of these emotions are unique to spiritual experiences.
