Therefore, some people have seen this situation and declare that Dantian is everywhere.
Because it requires practicing in motion, one cannot achieve a state of tranquility,
and neither will one's qi enter Dantian.
Feel your joints gently loosening and
stretching out. Then you will sense a heavy feeling in the Dantian area as you breathing out.
As you breath out, allow the abdominal muscles in your Dantian area to gently relax
and your lower abdomen to gently push out.
When they call it the upper Dantian, the middle Dantian,
and the lower Dantian, they are saying that Dantian is wherever dan can grow.
There are also some other
methods that teach you how to focus your mind on your Dantian, how to count,
how to fixate your eyes on objects, and so on.
