Step One Hundred and Twelve
Therefore, repeat upon the hour that you will remember Knowledge. Do not forget your practice today so that you may strengthen and empower yourself.
My initial response was - we forget Knowledge when we enter this world - but I am proceeding from the assumption that my soul has entered this world many times and each time the conscious mind is "liberated" from the baggage of its past. As a fetus in the womb and a newborn baby, I may still retain the Knowledge I succeeded in reclaiming in past lives, but it is soon erased from my memory as I deal with the immediate reality of a new incarnation. If my connection with Knowledge has been strong in the past, I may be lucky enough to begin remembering it again this time around and even build on what I reclaimed before.
As for the story about the Garden of Eden, if I take it as an allegory of the Separation, then it stands to reason that this was when we forgot Knowledge.
However, this all poses an even bigger question for me. Not "when" did we forget, but "why" did we forget?
