According to Osho, intellectual activity is a pseudo substitute for intelligence and cannot be truly creative. Intellect manufactures repetitions from the head and ego; intelligence creates from the heart by courageously entering the unknown and becoming a humble medium of the divine. Real creativity arises when the 'I' gets out of the way, allowing existence to flow through.
Just thinking hard makes copies; real newness comes when you quiet your head, open your heart, and let life move through you.
