The heart chakra is located in the vicinity of the solar plexus. In diagrams the solar plexus or fourth chakra is pictured as being in the front of the body rather than the back like numbers 1-5. I wondered why this is?
The cycle of the microcosmic orbit is from the Tan Tien or Perineum, up the back to the crown and down the front, through the hard palate and tip of the tongue, chin, throat, solar plexus, genitals and back to the Tan Tien.
What I came up with was that the flow of energy goes from Earth to Heaven and then to Humanity (represented by the heart).
Is that the way experience/existence should be filtered? Experimentation shall ensue.
EDIT: (1/30/12) — What if experience is actually best absorbed in the reverse direction and response is filtered in the above manner? What if experience is best absorbed through the heart chakra? My intuition tells me this is very important.
