What is the difference between thinking and understanding, reaction and response, belief and faith, sympathy and compassion, communication and communion?

According to Osho, thinking is borrowed, repetitive mind-chatter, while understanding is fresh, present-moment insight born of silence. Reaction is an automatic past-based reflex; response is a total, here-now intelligence meeting the challenge. Belief is second-hand opinion; faith is trust arising from direct realization. Sympathy feels for another from separation; compassion shares and serves from oneness. Communication trades words; communion joins beings in silent presence.
