Sub-planes of mind/body/spirit complexes in our space/time

[GentleReckoning]

Does unconditional love never waver? If you lose it and then get it back, is it unconditional again? Or does lacking unconditional love for a bit negate its existence?

It is unconditional love with wisdom. You move towards the negative and back to the positive as you reinforce boundaries so that you can more powerfully protect your unconditional love as you do work in 3rd density.

Placing the mental body (the negative body), in the way of energy always feels uncomfortable at first, but it is designed in such a way that it becomes very good at managing and mitigating discomfort. Eventually, you simply find people that make much better use of your unconditional love, and then it can flow freely again. (aka serving less shattered sixth density entities)
