Hi Venerable Brahmali,
I just finished reading some of those articles you recommended. I found the idea of the brain and mind being separated particularly interesting.
In ancient China, the mind and heart were one in the same character: 心. What’s interesting about this is for every other organ in the human body the characters contained a symbol for flesh: 月 (it also means the moon). For example, 脾 (spleen),胃 (stomach),肾(kidney),胆 (gall bladder),肝 (liver),肺 (lungs),肠 (intestines) etc. The character for brain 脑 ‘nao’ also had the flesh symbol. The mind was seen as nontangible. This idea of the nontangible mind permeated all Chinese thinking.
Within the heart/mind resided the 神 ‘shen’ - this is hard to translate, in its yin aspect (tangible aspect) it is seen as someone’s complexion, the yang aspect (intangible aspect) it can be loosely translated as someone’s aura. Not in the sense of glowing or being seen, but the feeling someone puts off. In Chinese Medicine, nearly all issues with the mind/shen are treated from the heart. A good example is insomnia. From a biological point of view, blood quality and its free flow play a vital role in mind health. Issues with the brain on the other hand are normally treated from the kidney or the body as a whole.
The heart is represented by fire, while the kidney is represented as water. In China, they are not elements though (different to India). They represent movements, fire is of course up and out. The earliest Daoist meditation (actually there were no Daoists or Daoism back in those days) was focusing on the breath in the abdomen. To do this one had to put the 意 - the minds intent into the abdomen. This meant that the heart fire was underneath kidney water which in turn makes steam. The character for qi is a symbol steam coming off rice. The abdomen was seen as the engine room of the body and was therefore called 气海 - sea of qi, the opposite spot on the back was called 命门 - life’s gate and was seen to store was we nowadays call DNA. By putting the mind in the abdomen it was believed that the energy room of the body would be tonified (this was all to do with the Daoist aim of longevity) and it was also done to anchor the mind or give the mind an anchor as one was focusing on the lowest part of the human body (it’s not the feet… where is the bottom of the Earth).
This is why nearly all tranquilizing medicine in Chinese Medicine is either minerals, bones or shells (heavy substances). They were meant to anchor the hearts fire so it would meet with the kidney water. In other words, bring the fire make into the abdomen. The question is, whats make the heart fire pathogenic or not stay in the abdomen? The answer is anger, over excitement, overthinking, holding the breath (as in lifting weights), sleeping late, an excessive amount of physical movement, over sweating; in other words forms of external stimulants.
The examples of this separation between brain and mind go on and on. The three most well known ‘internal’ martial arts in China are, Tai Ji, Ba Gua and Xing Yi. Internal means the aim is to develop power which issues from the centre of the body outwards. External (like Karate) means power is issued from the hand, arm or shoulder. Xing yi which means ‘form intent’ was originally called ‘xin yi’ which means heart/mind intent. The entire martial art was based on how to use the intent of the mind to develop power.
I’m wondering if there is anything in the Buddhist Suttas where the mind and brain were separated…
