According to Osho, innocence and ignorance are worlds apart: ignorance is darkness, negativity, an unconscious 'zero-state' of secondhand knowledge, on the same spectrum as the knowledgeable mind. Innocence is light and consciousness—a fresh, childlike not-knowing suffused with awareness. Ignorance is relative and gullible; innocence is alert openness beyond beliefs and expertise, seeing reality directly.
Ignorance is being in the dark and easy to fool; innocence is bright awareness without borrowed ideas.
