According to Osho, beginninglessness names reality’s eternal suchness: it has no first moment and no last; it simply is. Because the mind is time—past and future—it cannot comprehend the beginningless. Only by slipping into no-mind, resting in the present (eternity), can one know this directly. The knowing is a silent, loving, poetic insight, not a mental explanation.
Reality never started and never ends, and you can feel it only when you stop thinking and are fully present.
