"Know Thyself. These words were inscribed above the entrance to the temple of Apollo at Delphi, site of the sacred Oracle. In ancient Greece, people would visit the Oracle hoping to find out what destiny had in store for them or what course of action to take in a particular situation. It is likely that most visitors read those words as they entered the building without realizing that they pointed to a deeper truth than anything the Oracle could possibly tell them."
