According to Osho, naivety is ignorance while trust is the highest intelligence. Both may be deceived, yet the naive feel hurt, angry, and soon collapse into distrust. The trusting don't lose heart; they respond with compassion, understand human frailty, and their trust deepens. Trust values awareness so highly that one is ready to lose everything else, but never the trust itself.
Being naive means you don't know and get upset when tricked; trusting means you know people can fail, but you stay kind and keep trusting.
