That's right.
I think when Contemplatives and Orthodox speak of "the Spirit" quite often we mean more accurately our 'conscious contact with the divine' or our current state of grace, lack thereof, or our current spiritual condition
I don't know if you are Orthodox or not, but your mindset is.
This can be a state of being or consciousness that we are aware of, and it may also include an almost bookkeeping accounting of our unrepented sins and the purity of our heart
You said it again. :)
Spiritual growth then is a more, I believe, tangible or intuitively known state of being or intention. It is, in large measure the condition of our heart - which is the perceptual organ, eye, that is used to know God. And through askesis and God's grace this develops over time into more constant conscious contact with God
Look inside!
This is different I believe than how I see others talk of the Holy Spirit
This is Orthodoxy.
Latin. Mostly of the contemplative 'school.' I'm currently studying Orthodox practices and I'm finding, not surprisingly, it's mostly the same - with some Greek words. :)
Though as I said much earlier, contemplatives are not seen as mainstream in the West as in the East, or at least that's my limited impression and experience.
