Eucharist and mysticism are of-a-piece, that is, two aspects of One Sacrament.
Eucharist is the physical aspect of provisioning and mysticism is the psychic aspect of understanding pro-vision - what is the self-consciousness of pre-vision - what we call 'soul'.
Sacrilege does violence to soul - it desecrates Eucharist and Mysticism - it's happening all around in cultural arrogance and in the mindless wasting of Nature - what is SIN.
