As Eckhart Tolle says in "Power of Now"

This is one passage from Eckhart Tolle's book"power of Now" which I loved reading and appealed to me most.

If you are drawn to an enlightened teacher, it is because there is already enough presence in you to recognize presence in another. There were many people who did nor recognize Jesus or the Buddha, as there are and always have been many people who are drawn to false teachers. Egos are drawn to bigger egos Darkness cannot recognize light. Only light can recognize light. So don't believe that the light is outside you or that it can can come from only one particular form If only your master is an incarnation of God, then who are you? Any kind of exclusivityis identification with form, and identification with form means ego, no matter how well diguised.
