These days, I began to read the classic book "The Tree of Yoga", in which there is a passage that "water flows into the turbine like a waterfall, and the turbine rotates to generate electricity under the action of water. So is the human body. When we do asana, blood flows to every cell, just like water flows to a turbine, and the hidden energy in the body is released, bringing new vitality to cells. When cells have a new life, we experience the second principle of internal cultivation-satisfaction. "

After reading this passage, I was deeply touched. I suddenly understand why you sometimes feel relaxed, happy and satisfied after practicing yoga. It turns out that through yoga practice, our inner energy is activated, which not only improves our physical function, but also brings spiritual gains.
