According to Osho, the will of the Unknown (Brahman) is the ever-unfolding flow of existence. As long as you remain a separate 'I', you cannot know it and you struggle against it; this struggle breeds anxiety and suffering. When the ego dissolves, there’s no personal will left—you live as an instrument and witness, effortlessly aligned, joyous, and free of doer-ship and burden.
You’re like a leaf on a great river: stop trying to control the current and let it carry you, and the ride becomes easy and joyful.
