According to Osho, he won’t speak for other enlightened beings, but he himself does lie. He implies enlightenment doesn’t impose uniform behavior; masters may use unconventional means. Rather than fixating on literal statements, he points to the purpose behind them—to catalyze understanding. Thus, whether such lying is 'compassion' depends on the intent and effect, not on a blanket rule.
He won’t judge others, but says he does lie; what matters is the intent and whether it helps awaken you, not strict literal truth.
