Recently I happened upon an online posting of an image of the Reiki practice depicted as an iceberg. The part above the water line was labelled as the hands on practice and the bulk of the iceberg below water as a meditation based practice.
I didn’t have an issue with the iceberg concept as a metaphor for the contrast between what you see, as against the unseen aspects of the practice that are the experience.
My disconnect was with the inference that the the hands on treatment practice (the bit out of the water) was the lesser part of the practice, and that the larger unseen portion (labelled as a multi aspected meditative practice) was the most important part.
For me, the bit you can see, the very human “hands on” physical practice on oneself and with others holds an aspect that is of its very nature meditative or mindful, is a complete “wholing” relational experience, that leads into the deeper experience.
There is not need for “more” than that. This has been my experience.
