Do bad things happen to teach us a lesson? Thus, being a good thing in the end, because from that “bad thing” comes growth?
That is absolutely correct, things that happen are only good or bad depending on how each subject sees it. Things may be desirable or undesirable, but the action itself is neither good nor bad. There is no objective quality of “good” or “bad” to our experiences.
There is so much happening in each moment and we can choose what we focus on and how we see it. It may be harder or easier depending on the person and the situation, but we can always develop our focus, deepen our awareness, and nurture our ability to see the positive. We can choose to learn and accept, or resist and fight.
