Macrocosm is the same as microcosm. Universe is the living body with trillions of beings as its cells. Revealed countless times to yogis in Samadhi (meditation trans) since antiquity [0].
The microcosm and the macrocosm are vastly different with one exhibiting quantum behaviors and the other mostly influenced by gravity.
The experience of yogi's or Buddhists of a removal of psychological barriers that separate subjective experience into a personal and extra-personal world are just that. Changes to subjective experience. That means a change in brain state. It doesn't imply some kind of magic that changes the observed world.
Because things seem alike in imagery or language doesn't even remotely mean they are alike in observation.
What you are saying isn't unlike someone equating the Bohr model of the atom with a solar system. They do look alike in illustrations, after all. The problem is that solar systems don't look like atoms and they are vastly different "things".
(A change in brain state is a change in the observed world.)
