Greetings from the mountain top…
One of my gurus, a foul-mouthed, rough-edge janitor named Eddy asked me a question once which stays with me to this day. In this simple question the entire purpose of our many lifetimes was encapsulated, while also being coated with an intensely complex riddle.
“Kid…are you here to learn new stuff or to remember old stuff?”
Peace out ya learning freaks

Both in my opinion. New learning is what a person gets when they choose not to learn from someone who has already learned what they are fixing to learn. Remembering the past hopefully helps one to embrace new learning and avoid repeating mistakes that keep one from new learning. We hate breaching our comfort zones which new learning requires.
