What does it mean to be self-sufficient?
Logically it would be to take care of yourself in all ways without relying on others. Taken to the extreme would mean living completely by yourself and your own devices. That’s not possible for the first years of our life.
If we look at it from the perspective of sovereign self-sufficiency it gets more exciting. Sovereignty being your ability to be in charge of your energy space.
As Intimate Alien said, “You already created everything, now just allow it.” Doesn’t that sound like self-sufficiency?
You are a Divine Being. Quantum physics talks of infinite dimensions. We talk of the quantum field or the field of all possibilities and collapsing the wave. And, there really is no time.
If we are Divine creators, having already created every possible variation, then we are self-sufficient, and we can allow what we want.
