The older I get, the more I realize that our choices in life come down to two options: benefit me or benefit others. The first one leads to nearly every trouble we have in the world. The second nearly always leads to happiness, whether directly or indirectly. Our bias as humans has always been toward the first, but our evolution is and will continue to slowly bring us toward the second option. Beyond simple reproduction, this realization is our purpose, in my opinion.
He was a physics grad, did some experiments with out of body experiences, decided the Universe is a simulation for immortal consciousness to experience making choices and dealing with their consequences, and reasoned from there that the purpose of life is to get rid of ego and fear and learn to benefit others instead of ourselves.
Quite how he got from one to the other isn't clear to me, or why it's physics related; the message seems to be a familiar religious one, deal with whatever struggles happen to you and try to be egoless and kind.
