I drove to Bellevue a few days ago to spend an hour in a sensory deprivation tank at a yoga teacher’s home studio. I had intended to spend the day preparing for it: I went to bed early, and when I woke up I drank no caffeine. Unfortunately, bad dreams and a body sore from a rough massage put me into a foul, foul mood, and I spent all morning trying to distract myself from my desires and my regrets.
It turned out that my foul mood couldn’t have been more effective for a first float tank session, because an hour in the tank replaced negativity with a serious sense of bliss. The man who owned the tank had me shower. I walked through his yoga studio into the back of his house to join him in the tank room. The tank was an oval-shaped pod about six feet tall and probably eight feet long. Together we removed the cover from the inside of the tank, and he explained how I needed to be careful of my eyes, as the water was extraordinarily salty. We had part of the cover off, and he had me jump in. I disrobed - you float nude - and got in clumsily. Slow down, he said. You really need to slow down. I laid back. The water came up the plimsoll line just in front of my ears. I put my feet flat on the floor of the tank. I put a rolled up floating pillow under my neck and lifted my feet. I put my hands above my head with my palms facing up and laid there. The other option was the hands down by the waist, palms down, like the Vitruvian man. It was pitch-black, silent, and I was laying in a slimy, room-temperature solution. It took a long time to begin to take value from the experience. I laid there worrying and thought about the term “monkey mind”.
I really tried at first. I have found that with inner-facing experiences like this, getting rid of my preconcieved notions tends to happen within the actual experience. I tried to relax, tried to observe myself not relaxing. I kept my eyes firmly closed, which didn’t work. I found that my legs were tensed even though they were nominally floating, and I actively relaxed them. This helped, and a moment later I went through a progressive relaxation which immediately changed my posture from something flat and rigid to something genuinely *floating*.
Things got serious then. I had a sense of my body being separate from my mind. I started to feel separated. It was interesting that my mind could act even in the absence of stimuli.
I felt a sense of amphibiousness, as if I was drifting between media.
The flatness of the experience was interesting: my only open areas of movement were on one plane. I hit the side of the tank a few times and gently pushed off each time, so I barely moved. After the first time, I had the sense of being in strong motion/non-motion for the rest of the session.
I did some basic self-hypnosis. I wanted to find the answer to the question “What’s the next phase of my personality?” and I have found hypnosis very effective in identiying answers like that. I didn’t get an answer.
I kept thinking about how the letter R is a stylized spiral, and how I had built delay into my desires. At some point I dozed off, or fell into something that was sleep-like. When I came out of it I was unable to comprehend the darkness caused by having closed eyes from the darkness present when my eyes were opened. Afterwards, I got out and showered. My foul mood was completely gone. I was moving much more gracefully, less clumsily, than I had before. The yoga teacher gave me a hug and I left. Someone had called me and left a message I couldn’t understand on my cell phone.
It’s about two hours after the session. I’ve got a sense of total bodily relaxation that transcends any massage I’ve ever had - my muscles and tendons feel stretched out in interesting and natural ways. I have that sense of bliss you get from having positively spent your energy on something.
Other effects: Driving home, I wanted to minimize my sensory stimuli. I have found this is very common after inward experiences: I don’t want to use headphones or listen to music or watch television or read. The most valuable experiences, for me, are those that result in the positive feeling of “being” without pushing outward against that feeling.
