Hello, yes, that was a typo, sorry.
Embyronic Breathing as Dr Yang describes is when you keep your mind in the center of your Upper Dan tian in the area of the pituitary and pineal glands, and at the same time keep your mind in the center of your lower energy center. The energy is focused in the center of the body, and the mind becomes very quiet, reaching a neutral emotional state with no thoughts arising. Then, when you are able to hold both of these centers in a very calm state, use your Shen (spirit) to build Qi in the lower dan tian to an abundant level. Through deep abdominal breathing you generate a lot of Qi. By having a strong hold on your upper center you are able to lead all of the qi in the body to accumulate in your lower center. This boosts the immune sustem quickly, and will give you some abundant Qi to circulate in your practice.
In Buddhist and Taoist traditions, you also use Embryonic Breathing to unite the Shen and Qi in the Huang Ting area, above the lower dan tian until you 'conceive' a spirit body 'embryo', and eventually once it is strengthened, you will lead it up to the upper brain, and out through the third eye area.
For most of us, Embryonic breathing is way to reach deep levels of relaxation, and to get to a state of maintaining the brainwaves between delta and theta - a waking dream state, in which your awareness expands, and you have strong moments of clarity during which you may have a stronger experience of the true nature of reality. This is called samhadi in Buddhism. Eventually you can maintain this state for longer periods of time, and at a higher level - even during daily activities. This is very difficult, and it is the first of many stages of training toward true enlightenment.
Or so I have read.
Again, 'qi psychosis' is mental illness, insanity. It happens when you build up extra Qi and lead it into the brain before you are ready. If you can't hold the upper center strongly, the Qi energizes the brain, and sometimes if the mind is in a more 'open' state, this energy will make you have a million thoughts, hallucinate, or even cause permanent mental illness. So, don't fry your brain.
Regarding faciae/tendons etc - this is the basis of of all Dr. Yang's qigong theory. The tendons, sandwiched by fascia, are an electricly conductive battery, capable of storing and releasing Qi. I recommend you read his books, esp. the latest: Qigong Meditation - Small Circulation.
When I go from point to point its softer, because the qi flows there by its own.
The words to describe this are different for everyone. I think the 'point-to-point' circulation method is good. You can't PUSH Qi - it must be LEAD. So, by putting your mind in each point, one by one, the Qi will naturally follow. Often this is easier for some than to visualize than the entire vessel at once, so it is more effective.
Hope you're well,
