When judging the results of your own actions, you can’t simply take your own ideas of ‘what works’ as a trustworthy standard. After all, you can easily side with your greed, aversion, or delusion, setting your standards too low. So to check against this tendency, the Buddha recommends that you also take into consideration the views of the wise, for you’ll never grow until you allow your standards to be challenged by theirs.
