This definition, you can imagine it as a way to cross the latitude of space. Buddhism turns a bodhisattva into a devil, because when Sakyamuni was alive, there were no dolls, and he was afraid that later practitioners would "photograph" and would not regard stone and wood as Buddha. Look at the Buddha statues in the temple. Their handprints and standing postures are different. Because their gestures and handprints represent different meanings.
However, the roots of later generations are more and more easily lost. The Buddha failed to protect all sentient beings in the world, and because of the intangible merits of support, worshipping Buddha is becoming more and more common.
