According to Osho, trust is the dropping of doubt—the fall of the mind—and only in that doubtless space can witnessing arise. Doubt feeds thought; thought creates ripples that keep you a thinker, not a seer. Trust is not belief but total acceptance of what is. In this contentment, thoughts settle and the sun of witnessing dawns.
When you truly stop doubting and accept things as they are, your thoughts quiet down and you can simply watch within.
