When you accept the human existence, you do so with the understanding of its process. Regardless of the state from whence you came into this incarnation, you must navigate the path of being human again. And this is what each of you is doing.
“Why would we want to continue to do this if we don’t have to?” (Me asking)
You realize the value of the work. It is rewarding and brings you joy when you gain complete understanding. And even prior to this understanding, it brings you joy. The only difference is the level of awareness you are operating from when “doing your work.”
