Emotional response is only one small part of the Spiritual equation

Why should emotional response be anything other than a very human, earthbound way of reacting to things? Why does it need to be glamorised by any notion of mystery? Or shall we call it "spiritual" until the day we discover those exact chemical pathways, then just call it "ordinary"? I don't want my emotional responses to be in any way divorced from the everyday, thank you. Just because we don't completely understand their biochemical basis there's no need to stick mysticism into the space. That's exactly what religion does. Hey, have I just spotted something? :-)
