Mastering the lower Dan tien must occur first .
Understand the lower diaphragm and the space there below the umbilicus/navel. The space there needs to be developed over time. We may use the Ren 4 “Guan Yuan” or Ren 6 ” Qi Hai” point to help get to the Dan tien, but Dan tien is a space inside the body and not on the surface. Place the ‘mind in the dan tien‘. Mind should inwardly gaze and observe the expansion and contraction in this lower body area where small intestines are located. We then ‘sink to the dan tien‘, the heavier elements naturally move downward and relaxed, this allows (qi/yang, and yin/blood) to generate warmth, lastly we ‘grasp the qi in dan tien‘ where everything in the dan tien is now anchored to pull and push oxygen in and out naturally and non-forced. Once achieved, we can call this ‘dan tien breathing‘. There are two main types of this breathing. Fetal breathing when belly expands on inhale and contracts on exhale, also known as natural belly breathing. Reverse breathing is when you inhale and belly contracts, and exhale and belly expands, this is will used at certain times as well.
A great amount of time needs to be placed in lower Dan tien and cultivated until you feel the space open up and fill like a ball expanding and contracting with lower diaphragm breathing. Beginners, recommend 15 to 20 minutes either sitting cross legged or standing in Wu ji stance. Try at minimum 30 minutes once you advance and then work your Taijiquan or Qigong forms after.
