To seek knowledge because it is forbidden is the seeking of power for personal gain. One might do so because they are scared or to hurt the one who forbids. If you are seeking truth it doesn’t matter if the source is forbidden or not. For example I know a bit about things from esoteric sources, but I didn’t seek them for that purpose. I started because I was seeking truth about health and growing plants and came upon biodynamic farming. Now I picked up the pace when I had my girlfriends health to concern me and that wasn’t 100% altruistic. Thankfully I’ve enough discernment to have stuck primarily to sources that have ennobled my desires and now I continue to learn but less out of fear and personal gain than I started with.
Truth can be sought in every day things. A well made tool, a beautiful person, even a Disney villain who truly embodies evil and is depicted as being ultimately defeated.
