Over many lifetimes we eventually come to learn, and feel, the interconnectedness of all life. The same life energy that flows though us also flows through other people, animals, plants and trees.
Sometimes we feel separate because we focus more on the “containers”, or bodies, that hold our energy than we do on the energy itself.
When we are eventually able to recognize that we are all the same inside, we realize that our connections go beyond our “containers”. We realize we are not separate and we are never alone.
