Thanks for the replies!
Yes, my understanding of all this is “still developing”. I’ve read all of the 11 references in the ‘sincerity’ catalogue.
I can see that a quality of ‘innocence’, as in “lack of guile [i.e., sly or cunning intelligence] or corruption; purity”, by definition naturally exists in being sincere. This ‘innocence’ is not a feeling (as in, “Whoa, look at me, I’m such an innocent angel”) or a moral-feel-good’ism, but a simple matter-of-fact quality of how “I” can approach everything perceived or felt. “I” am also naturally cunning, however, so allowing this quality naturally involves recognizing and ceasing all those should-nots, can-nots, will-nots, etc. inasmuch as they mask the simple facts of the situation. Also, I see no reason to be serious, especially on a day-to-day basis I continue to survive and thrive anyway (I’m neither homeless nor living in a wartorn country, for instance). Even the ‘panic’ of December need not have been such a serious issue (I could have had fun with this ‘love’ business so easily, in hindsight).
Also, yea, it has been very tempting to ‘get on with life’ instead of taking a good look at what lead to a recent diminishment. I’ll particularly pay attention to this.
Okay, so sincerity = staying true to the facts. I get it. That’s enough for me for now.
