Are surrender and enlightenment simultaneous events, and what does it indicate when a surrendered disciple undergoes years of practice?

According to Osho, surrender and enlightenment happen together: the instant real surrender occurs, enlightenment showers with no delay. What most call surrender is only rehearsal: long practice where the ego is cut inch by inch. Years of effort by a so-called surrendered disciple simply show preparation and cooperation ripening, not the final act. Blessings help, but you must open to receive; true surrender dissolves you, and then it is done.
