Is it easy to be possessed by Zhouyi?

Not because I learned Zhouyi, but because of my heart. George, a friend upstairs, answered very well, but even if you learn to predict fortune-telling, you may not be possessed. It is your state of mind, not external things, that is possessed. If you are calm and natural, you won't lose faith even if you are in a desperate situation. On the contrary, if you are uneasy, you will toss and turn even if you lie down.

What is superstition? Stubbornly believe Learning Zhouyi is a good thing. I hope you can cherish this opportunity.
