Peter talks about aligning with principles - such as honesty, mastery, etc. - instead of living from one's own "small self" (my framing), driven by fears and desires. It feels to me that love is also a principle. What I mean by love is doing something purely for the benefit of others, without any expectation of a reward. I am not really sure I can frame it as a principle, I suspect my understanding is still too vague. But there is something. I'll keep you posted :)
