According to Osho, the ‘mystery’ is simple: all genuine masters pour the same wine of truth into different cups. People cannot hear directly, so the wise use familiar names—Buddha, Mahavira, Krishna—as compassionate “screens” and languages the listener trusts. The essence never changes; only the packaging shifts to meet oblique minds. When direct seeing returns, the screens can drop.
All masters teach the same truth, just using different names and stories so people can understand.
