Is there any truth in the mysterious Feng Shui theory that "images are formed in the sky and images are formed underground"?

That makes sense.

To break the knots of acupuncture points, some people say: a first-class earth master watches the stars, a second-class earth master looks for the water outlet, and a third-class earth master walks all over the mountain! First Class Earth Master Observing the Stars: What are the Stars? A first-class Earth Master observes the stars by looking at the star (Luantou or Liqi) in the Xinglong star body to determine the shape of the hole. The star is a dragon, and the five elements are interdependent and enter the hole. There must be no gap! If they conflict with each other and enter the acupoint, although the situation is beautiful, good fortune will come last but misfortune will come first! Whether it is a blessing or a curse, it all depends on your Taoist eyes and your fairy eyes!
