According to Osho, Jesus feels like a stranger because he actually is one: he lives in another dimension—God—while we live in the world. Catechism gives second‑hand words that breed complacency and block direct knowing. Only meditation, silence, and dropping beliefs make you inwardly naked enough to meet him. Without awakened intelligence and awareness, teachings become pillows for sleep, and Jesus remains outside.
He seems strange because you learned about him instead of meeting him; become quiet inside and drop borrowed beliefs to truly know him.
