To give context to the advancement of life...

[Adonai One]

In this octave, there is only light. Light as a concept only falls away at the 8th-density.

That sounds scary if the next octave is without light. I assume even Love falls away too.

Light is just a method of experience. In infinity, all is experienced. In infinity, all is loved and unity is inherent thus love becomes a non-concept. Love turns to eternally loved. When all is eternally loved, the act of loving becomes redundant and unnecessary for all is inherently known and embraced fully.
