Knowledge unites, in being or in identity. Thinking separates, in subject-object relationship.
Knowing has no place in the ordinary thought process. Thinking about something
which has to be known is wrong, since it moves in a vicious circle. You cannot think
of anything you have not known. Such thinking can never take you to the Truth.
But when you direct your thought to something (say yourself) which you have otherwise
visualized, the thought loses its own characteristics and limits, and stands
revealed as that Self (Consciousness) itself. Thought is thus reduced into its essence.
