Our Other 7 Bodies: What They Do?

In the western world, one physical body is generally acknowledged as real or applicable to existence. In the east, it has been long understood and acknowledged that more bodies than our physical one exist and function in our objective/subjective daily realities. I talk about these 7 other bodies in the order they are layered and the way they connect to our bodies and other systems. I talk about how they are layered from physical to gateway to other existential ports.
There is more to life than reality.
