98 Taoist Secrets Of Love
This polar exchange is overlooked because the flow is invisible
to the physical eye, and because its workings are often too
subtle for the uncultivated mind to perceive. That is why Taoists
study the workings of chi, ching chi, and shien. These energies,
also called the three treasures of life, are the subtle language of life,
and to speak in them properly takes years of practice and refinement.
At first approach it may seem like learning a foreign language.
But after a few lessons you quickly realize you were born
speaking this language and merely forgot the subtle grammar of chi
energy while being intensively schooled by parents and teachers in
more mental subjects.
