When I take DMT, there is a large energy component to it (it seems to be a component on which the entire experience is derived), and through some practice and meditation, I've learned to harness the energy to some extent while sober. It's a very physical feeling thing. It has a force to it that moves my limbs autonomously upon contact. Through much experimentation I've found that this energy is directly connected with attention as well as breath. One day while I was studying one of my crystals, holding it up close to my face so I could examine it, my arm began oscillating forcefully back and forth as if the crystal had a magnetic attraction/repulsion with my face.
So of course I come to theorize that perhaps it was interacting with my third eye chakra, so I decide to hold up the crystal to other parts of my body to see if I can elicit the same energetic effect. It doesn't really do anything when I place it just anywhere, but when I put it in front of my throat, I got a very large effect, as well as with the solar plexus and sacral chakra. The only chakra it really didn't seem to want to work with was my heart chakra. When I placed it in front of that chakra, nothing happened. There was absolutely no energetic activity like it was a dead spot. I tried different crystals...nothing. As I sat and thought about chakras and what I had heard about them, I recalled that the chakras were all associated with different glands and organs.
So "there it was" I thought. If the chakras are aligned with the different organs and not perfectly straight down the spine, then the heart chakra would be offset to the left. So I took my crystal, held it in the center of my chest: nothing happens. I hold it on the right side of my chest: nothing happens. I hold it on the left side of my chest: eureka! It was like turning on a battery. My arm began forcefully oscillating back and forth. It is because of this experience that I believe in chakras. I feel I can say that it goes beyond subconscious auto-suggestion or something of the sort because according to my prior beliefs, as far as I knew all the chakras went straight down the spine (as it is so often depicted) and so by that logic, my arm would have been oscillating where I had initially believed my heart chakra to be, but that just wasn't the case at all. I think several days had elapsed even before I made the connection with the offset organ.
