According to Osho, silence is indispensable one step before buddhahood, not the final state itself. At culmination, realization ripens into compassionate expression: the Buddha spoke for decades. All arrive through silence, but not all choose to speak; those who do become true masters, sharing what cannot be given yet can be shown, letting eloquence arise naturally from inner emptiness.
First you become very quiet to wake up, then love may move you to speak and help others—though some awakened ones remain silent.
