I am always happily amazed when discrete categories in a threaded idea always seem to overlay, intersect, and form a continuum.
In the KY activity, the aim, as it should, creates the field in which the Karma of KY plays out. Subtle interest, which I 'ahahed', was really desire. That subtle desire for acknowledgement, praise, status, etc. becomes the tail end of becoming a non-doer. The non-doer is really the Universal Ego.
Foregoing the fruit of action is non-attachment. The more we become non-attached, the more we operate in the present where we can be aware of our subtle self-interest, become a non-doer, and merge in Universal Ego, the Self.
