Sophie111:
May I politely suggest this seems a tad heavy on the superstitious. According to Magisterial sacramental teaching (as opposed to some extreme, flavour of the month, free lance internet exorcist) the salt and blessed water has no inherent objective efficacy in such spiritual matters whatsoever.
It’s an act of faith claiming this ground, this room, this space for Christ. We dwell in a false dichotomy between the spiritual and the material world in this present age, but the God Who comes to us in a wafer of bread does not hesitate to confer sacramental grace through holy water or salt.
It is good that @berniemcken experienced the grace of Peace. Thanks be to God!
