Cleansing can contribue to a sense of ease (while coherency is sought through cleansing), as it works like a harmonic of the same expression, only at another level. Physical, emotional, mental, and spiritual "frequencies" just repeat over the "scale" of consciousness. So working in one part of the spectrum leverages another part of the spectrum because indeed they are the same only differenicated by interference patterns that creat the illusion of difference.
So working on coherency in the area of the physical body will also work on the emotional, mental, and spiritual levels because in actual fact they are all the same.
Just like the note 'C' repeats up and down the scale, so it is the same with the frequencies that make up the "experience" of life.
