Any true wisdom, as ethereal as it may be, sits above your head as a massive reservoir of living waters. Provide it only a small opening, and it will burst into your reality and pour down into your life.
Whatever wisdom you learn, whatever you know, do something with it. Make it real.
That is the purpose of meditation and prayer—to be that bridge from wisdom to action.
