Az embrio légzés egy állomás, nem gyakorlat:

"by Li Shi Fu (Five Immortals Temple)气蛰脐下，曰胎息。—大成捷要When Qi hibernates below the umbilicus, it is called ‘Embryonic Breathing’.—Essentials of the Shortcut to the Great Achievement Embryonic breathing is an internal breathing, in which one does not breathe externally through one’s nose or mouth. This first began in the womb when one’s mother’s breath became one’s own. If one wishes to practise embryonic breathing now, therefore, one needs to find a special connection, a new umbilical cord, as though one were still in the womb. Embryonic breathing is something you will slowly begin to experience during sitting meditation. It is also called ‘Elixir Field Breathing’. Once you have achieved this, you will no longer have any need to be afraid of life and death.There is a special condition that immediately precedes the stage of embryonic breathing. Just before one reaches that breathing, there is one last single breath that is very light and like a whisper. This is the demarcation line between external and internal breathing, which manifests as a physical feeling and might be very abrupt and abnormal, just like a chain that snaps, which is here the balance or link between Yin and Yang. This is a very cheerful, content and happy stage, as you feel like you could live forever. Usually, however, it is only a temporary stage that lasts for a certain length of time, which increases with practice. It also corresponds to the revolving of the microcosmic orbit. One needs to let go of one’s feelings to achieve it. That is why it is so difficult and it can take up to fifty years to reach this stage."
