According to Osho, certainly: life itself is the Master. No situation is without a lesson; only lack of awareness hides it. By staying watchful and examining all aspects, you can learn from everyone and everything—a dog, a thief, a king, a mistake. Openness transforms clinging into freedom, confusion into insight, and every event into nourishment for your awakening.
Yes—if you pay attention, every person and moment can teach you something that helps you grow.
