What is trying to be expressed by "highest form of wealth" is usually about agency.<p>The problem with agency, unlike what 'power' connotes you to believe; you can't just have and store it for later. Like others rightly point out in this thread, there are many avenues in life you want to be agentic but cannot solve with anything you <i>possess</i>, but only through <i>becoming</i> a required thing through transformation; examples are health, skillfulness, being understood in a relationship, an equanimous existence etc. Even then, you're to an extent up to the whims of misfortune and fortune, or if you're not allergic to that word; to fate. There is at least one thing you can't be agentic about with any wealth, and that is your fatality; which connects to the original meaning of fate.<p>But that's not even the only problem with agency; most of the time you don't even know when you have it and also when you don't have it. This is the bread and butter of psychotherapy; you either misattribute blame where it doesn't belong or fail to hold people/yourself accountable when you should; or you miss what and how you could solve a problem but instead invest your energy and emotions in an avenue that just won't work.<p>Which means agency, capability of doing things that get you towards your <i>real</i> goals, whether you've realized them or not, is deeply tied to <i>wisdom</i>; knowing in which manner you're deceiving yourself be it through buying things instead of being things, or getting out of being confused about whose agency exactly lies where and where is the way out of an agentic entrapment.<p>Which ultimately means, there is one and one only form of wealth, that thing you constantly need to aspire to build, and that is wisdom.
