In English
The physical heart is like the main switch for the mansion of human body. It is only the main switch, but not the ‘current’. Then where is the current? “Brilliant like a streak of lightning set in the midst of the blue rainbearing clouds ()”. Where is this ? This effulgent power is present in the spinal column. This is also called the central nerve current (). It is from this that the current enters the main switch of the heart. If you do not know this, you may enquire about it yourself.
