Perhaps - - just perhaps - - if one wishes to be fundamental about it all - - "spirituality" would apply only to the level of pure Soul and above - - which would "envelop and contain" Divine Spirit - - all of which is beyond the levels of duality / polarity / opposites / cause and effect / whatever word one wishes to use here to carry the concept. After all - - that which would be purely of Spirit - - would be "spiritual.
But Soul takes on the psychic elements to understand life here in these worlds. The mind and the emotions - - and all they entail / represent - - would be "psychic" in nature - - and not really "spiritual."
The physical world is somewhat separate from both - - tho I don't like to use the word "separate" here or anywhere - - but it gets the point across.
There are "reasons" for each point of view - - that of Soul - - that of the psychic preceptions - - and that of the physical.
All of this is simply something to consider. Sometimes - - a few "definitions" - - tho they are mental - - help to keep a few things straight.
