According to Osho, master-disciple transmission safeguards an inexpressible truth: while many may awaken, only the rare master can communicate the wordless essence. Buddha “said” it to Mahakashyapa through silence—the flower transmission—authorizing him to carry the secretmost key. This lineage appoints those skilled in conveying the unsayable, preserving authenticity and efficacy of awakening across generations (e.g., Mahakashyapa to Bodhidharma to Hui‑Ke).
Many can wake up, but only a few can silently show others how—so the master chooses the one who understands without words to pass it on.
