According to Osho, authenticity in spiritual teachings springs from direct, lived truth that speaks in one's own voice—spontaneous, intelligent, needing no memory. Borrowed words, however exact, are hollow counterfeits sustained by opposition and clever recall. Imitations inevitably arise around the real—like fake coins around genuine ones—so don’t be disturbed; see the laboring imitator with compassion, and trust the freshness that cannot be rehearsed.
Real spirituality is speaking from your own experience, not copying; fakes will appear (often while opposing), which only shows something real exists.
