Had a bit of a headache the last 13 hours or so, woke up still there and meditated and felt a lot of tension in my jaw. Once I let that go the headache was gone. Noticing the jaw brought me back to the eyes where I usually think to release based on a technique for relaxation and focus that I read by Gurdjieff many years ago. That fact has stuck with me for almost 30 years!!!
I found this quote after a quick Google search:
The fact that the eyes are accumulators is useful for a person who knows how to relax the eyes, and to bring consciousness to them. It means that the person can use the accumulators more intelligently, and, with a little further knowledge, gain access to the large accumulator, because the eyes have an indirect connection to it.
If I remember correctly the reference I am remembering was referring to Gurdjieff’s ability to recharge his energy and function on very little to no sleep, partly by not wasting energy on unnecessary tension, and also by access to some larger store of energy outside of himself. I assume that is the reference to the ‘large accumulator’.
