According to Osho, nothing is wrong—in fact, it's a sign of intelligence and innocence to have no real questions. Questions arise from inner disturbance and the urge to fix; when mind is open, it wonders rather than interrogates. Life is a mystery to be lived, not a problem to solve. Accepting 'I don't know' begins wisdom; when questions fall away, wonder and joy remain.
It's okay not to have questions—when you're peaceful and open, you simply enjoy the world like a child.
