Why are different names like heaven, earth, matter, and consciousness used for the silent manifestation of the unknown?

According to Osho, the Unknown/Absolute is beyond speech and remains unmanifest; whenever we try to express it, language splits reality into dualities. Thus sages use diverse names—heaven/earth, matter/consciousness—not as literal divisions but as necessary pointers within language’s twofold framework. Like a straight stick seeming bent in water, the One appears as many when refracted through words; silence alone preserves its unity.
