To know thyself, you must first question the assumptions you’ve made about who you are. In fact, everything we have taken as truth has to be questioned, analyzed, and reformed in a conscious manner, so that what we are, what the world is, and what the universe is can be approached as a great mystery—as a unique path that will lead us to a lifelong adventure of discovery.
To know thyself, as the oracle of Delphi commanded, and as Socrates told his students, is not only to know your identity—with all its preferences and histories—but to know that you are not that identity at all. It is to know the limits you have imposed on yourself. To know that manner in which you were educated by family, culture, country, and religion; and how they have provided limits for yourself, because they have created an avatar that functions on behalf of those very same religions, countries, and artificial human groups.
