Lightning - Elemental Room

Hi there. This is my first topic and I am quite new in blender. I’ve watched some tutorials and made some small pieces of my own (not perfect, or even close, obviously). So I’m modeling this temple room with 4 stones, each representing an element. The problem is i’m not very good with lightning, which i understand is important. The idea was to have a sun ray coming from the top into the middle circle on the floor, not messing with the lights emited by the stones. Does someone have experience with this? Thanks in advance!
