Gnosis is a universal pathway of ancient wisdom that is found in all religious tradition and spiritual philosophy, but must be practiced to be experienced.
"Man, know thyself and you will know the universe and its gods." Inscription at the Temple of the Oracle of Delphi
The world is like a dream where we go through so many motions having forgotten our true purpose. Why are we here? Is it to acquire wealth, friends, experiences, etc? What else is there? What brings us happiness and fulfillment?
Do we base our goals on those around us, on people who have made impressions on us? We truly know ourselves only as much as we truly know the universe.
Gnosis is experiential knowledge, the wisdom from direct experience which is always practical.
You are never expected to believe what is said, and everything learned is meant to be applied. When we continually apply these teachings, we will experience the awakening of consciousness.
