I came across this short article of a Michael channeling session that has Self Love as the main theme but it touches on many relevant topics. Especially the 4 Pillars that are supposed to build Self Love and help one fullfill one’s Life Task:
True Work, True Study, True Play, True Rest
These four categories have different meanings for each person, so an activity that would be True Work for me might not be for someone else. One way to find out what activities I could do to work on these pillars is to ask that in a channeling session, which I plan to do in a few months or so.
Here is an article that goes into these 4 pillars somewhat deeper.
