According to Osho, you can publicly declare yourself a world teacher and people will follow—but that’s an ego trip and spiritually dangerous, the blind leading the blind. True teaching flowers only from perfect disciplehood, when the ego is dropped and the Master awakens within. Resist the temptation; become a deep disciple first, and if it’s real, teaching will happen without self-proclamation.
Yes, you can say you’re a world teacher and get followers, but that’s just ego—first learn humbly as a disciple and let real teaching arise on its own.
