That which you know from deep observing, extensive inquiry and confirmation in your own experience - in any area, whether spiritual or worldly knowledge - has real authority. You should humbly admit and share that knowing rather than believe that "not to know" is always more true or wise. The goal is to keep your knowing open to change or deepening.
Who or what is the knower, and where is the knowledge? Consciousness is the knower, and the knowledge is held in the intellect or mind.
