a sound is good or bad. Please watch your ‘judging’ mind. That is part of the practice. Begin by just noticing sound. In your home. In the environment. In your body. Notice the breath at the same time, because there can be no sound without chi. To learn feng shui, you must understand chi.
To understand something like chi, you must experience it’s effects. Feng Shui has a strong experiential quality……it cannot be learned by the mind, alone.
