According to Osho, nonduality cannot be spoken; speech inherently divides, so sages use the minimal pair—"Heaven and Earth"—as the closest verbal pointer. The moment truth enters language it refracts like a straight stick in water, appearing bent into two. Beyond words only silence and direct experiencing remain; within language, dual terms are unavoidable.
Because talking splits the One into two, teachers say “Heaven and Earth” as the least-wrong pointer to what can’t be said.
