Gnothi Seauton - Know Thyself

Those words are inscribed above the entrance to the temple of Apollo at Delphi in Greece.

I don't know what to make of them, infact, I didn't know what to make of them until I read this & in many ways got answers to questions I didn't know how to ask:

"Nobody can tell you who you are. It would be just another concept, so it would not change you. Who you are requires no belief. Infact, every belief is an obstacle. It does not even require your realization, since you already are who you are."
