Spirituality, from a Catholic perspective, is the interior life of a person, shared with God, its regularity, its easy readiness to refer everyday matters to God, its naturalness, its directness, its familiarity, its simplicity, its sincerity (sincerity means "without wax", going back to the use of wax to fill defects by the sculptor in statuary..when we converse with God there should be nothing covering up our defects, imperfections, sins, etc.). 

A good priest I know said: "chatter with God, don't over intellectualize your dealing with your Father God, speak to Him as a child would his loving father, naturally". 

Today, while we have a body supporting our life of love for God, we use our body to keep this conversation with God going on (and some choose to use their body for other reasons than loving God).
