Band-Aids.  You use them to cover a wound.  You have an expression that something is “only a band aid” if it is not a cure, but a temporary solution.  Ultimately how does healing take place?  By the grace of God.  Just as does your breathing.  Medicines, band aids, healing energy, these are all helpers … tools that most certainly do work in concert with Source to effect healing, but again, ultimately it is Source that continues flowing through the vessel to return the vessel to stasis, to health, to balance.  Do all that you can to support healing.  First and foremost, know that a Power greater than any one individual unit of that Power is what makes the world go round.  Honor That.  Support That.  Being aware of That changes everything.
