Theres no true enlightenment without staring at the darkness and accepting everything it comes with, (which can be difficult at first) to enlighten is to brighten up a dark area, if youve only found happy wisdom, you haven’t yet incorporated both yin and yang yet. Once you find the deeper truths, dont fall into the trap of being vexted by it or trying to attack it, accept it and find peace with it, then you will have moved into the deeper states of enlightenment.
