What is the significance of saints and siddhas using abuses as a form of blessing?

According to Osho, when saints or siddhas hurl abuses, it is not hostility but a compassionate device to shatter your ego. Neither abuse nor praise has value in itself; the Master uses whatever cuts the knot. If he scolds or strikes you, it signals grace and your readiness—like a surgeon’s painful cut—to empty you so the Divine can enter; a single shock can catalyze awakening.
