answer:My practice has been rough lately, and I mostly only meditate about 20 minutes per day. But when I do, I find that the following happens: As my mind becomes still, my perception of inputs increases. There is nothing I experience that is in any way a sensory-deprivation chamber. Sitting in a “silent” room and getting settled in meditation opens me up to a plethora of inputs and sensations. There are the whole range of noises that I was not aware of before, there are body sensations, such as an itch or a tight muscle. There are vibrations from the furnace. Smells. Then, there are the whole set of thoughts and emotions that appear. It’s “silent”, but it certainly feels as though I’m sitting in the middle of an orchestra.
