Just a thought but while reiki is handon maybe you are being lead at times to be hands off due to one of two things;
first maybe the hands off is needed because what you are sencing has not manifested in the physical and there for it is more responsive to hands off.
Second is that maybe the persons highest self is ready for the issue to be healed and worked on but the lower selves are not in that same line so hand off may allow the area to receive some but not all ..
One thing I have discovered in reiki is that what a person does not want to be healed will not be...so that has always made me wonder well what about the higher self and lower self you know that subconscious part of us that know and sometimes we wish our conscious selfves were only more intune with that part of ourselves..
Just a thought?
