Finality, I love your distinction between feelings and emotions, and how feelings live in the body and all around us, while emotions are ego-interpretations of those feelings. This is a very useful concept, and helps greatly with the vigilance you speak of.
It also helps remind me that Reiki people are not learning to be un-feeling, in fact, letting go of attachments to emotions, clears the way for us to truly Feel.
That is how we honor our Oneness, by Feeling it!
Blessings,
