廟 combines 广 (building with a roof) and 朝, which likely contributes the sound and possibly the idea of facing or morning audience, suggesting a hall where one faces ancestors or deities.
Under a roof (广), imagine a morning (朝) ceremony at a grand shrine or mausoleum. The building is a sacred palace for honoring the past.
For ビョウ, picture a sick person (病, びょう) being brought to the shrine to pray for healing. The shared sound びょう links the mausoleum to the idea of illness and recovery.
