Kevin, I replied to the first of your links but not the second.  Having now read the second, I can only say that what you describe is a spiritualism or heightened sense of union with God that I have never known.  It was what I imagine is experienced by saints who have so perfected themselves that they are able to slip the shackles of their senses and experience pure spiritual oneness with God.  It is what I imagine heaven would be, the state to which Scripture alludes as having been lost by Adam.  You must be saintly to have even a glimpse of it..  My experience, unfortunately, is so much more mundane, literally; I have never been aware of such spiritual ascent except during the Mass, when I received the Eucharist.  It was overwhelming.  Although I still receive the Eucharist, I do not have those experiences nearly as often as I used to.  You are blessed to have these more frequent experiences of what a union with God is.
