Introduction to fiber optic ceiling: Optical fiber technology has safety features such as transmitting only light, non-conductivity, low-temperature transmission, and not afraid of water. It is a high-tech product of modern optoelectronics. Looking up at the ceiling on the top floor of the Hall of Ten Thousand Buddhas, steady and soft optical fiber shimmers are thirty-nine meters away, brightly and solemnly outlining the atmosphere of the Buddhist country. Ten radial indirect lights shine outward between the petals of the lotus, representing the layer-by-layer deduction and mutual integration of the ten dharma realms; and in the center, there is a pure lotus with layers stacked on top of each other. Observe carefully. When you look down, you will find that the center of the lotus is expressed in a hollow way, and it also represents all appearances, which will eventually return to the one true Dharma realm, impartial, neither real nor false.
