According to Osho, even if you take seven hundred years—like an Indian train absurdly late—you will still reach the station of enlightenment; arrival is certain. But postponement is unnecessary suffering: enlightenment is not in time, it is a shift in awareness available now. Board the train this moment—drop excuses, be present, and wake up.
No matter how long it seems, waking up happens only when you choose awareness now—so stop waiting.
