I am a biologist, and it has been freeing to learn that altruism can coincide with pleasure and be spiritually correct. Some courses I have taken would say that actions paired with feelings of pleasure can’t be considered truly altruistic because there is a “reward” of good feelings attached to it. That way of thinking definitely perpetuates a path of suffering instead of a path of light.
I expect that we learn more about the history of Kabbalah and important people that contributed to it throughout the years. I also hope we learn more about how to actually climb the ladder of the spiritual worlds.
