For as long as I can remember, I have suffered tinnitus. It's a high-frequency tone in my head, and it never stops. Tinnitus is recognized as a symptom of many causes. Stress, hearing loss, tumors, infections, medications, and ear wax are identified as causes.
Meditation has been a part of my life for a long time. Strangely, there is an obvious connection between my meditation practice and my tinnitus. The first moments of meditation are always the more difficult. Loosening my limbs, clearing my mind of events of the day, silencing the mental chatter. Eventually, I start to sink within. As I become calm and fall further into my mind, images begin to appear. At first, it seems like I am imagining shapes emerging from the fog. Soft, ghostly patterns, faces, and sometimes geometry appears and fades away. If I maintain my focus, the imagery becomes more pronounced. At this stage, the ringing in my ears grows louder. Colors begin to paint the imagery. First, soft and faint; with time, brighter hues and more vivid splashes of violets, blues, greens, and reds. The ringing grows ever louder, and then *snap* it drops sharply in frequency. My ever-present high tone is entirely replaced by a distinct, lower tone. Oftentimes this snap will shatter my concentration. This level is a difficult depth for me to attain and the excitement of achievement is often enough to bring me back up to the surface. If I manage to remain in 'second gear,' I can spend time in a delightful realm of bright colors, beautiful visions, and astounding geometry.
If meditation is like paddling in a canoe, then DMT is like being fired from a canon. I haven't dared to take a breakthrough dose, but I have a good sense from experience that that dosage is somewhere in the low 20s. What is important to me here, is the direct similarity (albeit enormously intensified) of the imagery and corresponding head tones between meditation and DMT. DMT presents the same first gear, second gear, and then novel third gear, which is a robust oscillating tone. At 18mgs it reaches a scary, near-deafening sound that feels like everything is about to be ripped apart.
The similarities between the two modes of altering consciousness fascinate me. Also, the experience with DMT has dramatically assisted my meditation practice because I have a much better sense of where it is that I am going. DMT has provided a struggle-free synopsis of a chapter that I have not read yet.
Meditation has made me question if my experience of tinnitus is more than a mere physiological phenomenon. DMT has me nearly convinced that it's a kind of concrete sensory feedback signaling and confirming exploration beyond the normal boundaries of consciousness.
