eiki works on a spiritual level because it prepares the body and mind thus enabling the whole body to prepare for spirit. Once your body and mind are prepared then you can see more clearly, know with certainty, feel with ease, and hear what you need to know.
The seven chakras are the main energy centers of the body. You’ve probably heard people talk about “unblocking” their chakras, which refers to the idea that when all of our chakras are open, energy can run through them freely, and harmony exists between the physical body, mind, and spirit. Chakra translates to “wheel” in Sanskrit, and you can imagine them like wheels of free-flowing positive energy.
