According to Osho, when a master’s presence overwhelms you, it exposes your hidden clinging and defenses; the ego resists, escapes, invents protective questions. No master can confer enlightenment; your openness decides. A compassionate master will dose the fire to your capacity and use devices to break fixations (like miserliness). If you come totally, transformation flowers; halfheartedness stalls.
Feeling overwhelmed means your ego is scared and starts making excuses; relax, be fully willing, and let the master help you drop what you cling to.
