had a bit of headache yesterday but then when i did exercise some jaw muscles (thus draining the entire head from lymphatic waste through muscle acticity). that helped and did some meditation, in fact i found out then when i am reading, i can do the most important meditative exercise that i know which is to shift the attention into what is called the inner body. so i am reading but i feel this electric glow in my entire body. it feels like a weak version of a strong orgasm but in the entire body and for as long as you want. nerves do not only transmit pain, since they are electric they also have a biological electrical field that you can literally turn on by moving attention from your thoughts into your body. attention controls your personal electric field yes. i literally feel pleasant electricity in my arms and feet and in the rest of my body until my entire body feels like it pleasantly glows.
this reduces the burden of unnecessary thoughts (thinking is a metabolic activity and creates metabolic waste) and worries and thus contribute to a clear head.
today i played tabletennis went running and went skating. no headache today, i guess because i read for like 3 hours in the sun and did my meditation while reading.
