A wise reminder offered in the wisdom teachings is: "Drink water from your own cistern, flowing water out of your own well" (Proverbs 5:15, ESV).

Water is the hieroglyph of the letter Mm. The Proverb counsel in the language of symbols is speaking of this renewing, transforming, and mystical letter. In this Proverb, the letter Mm is acknowledged for its subterranean intuitive wisdom residing within you.

"Drinking water from your own cistern …" is pursuing depths of wisdom and knowledge that is latent within you. The cistern lets you know that you have to go into your inner fountain of many depths to access the wisdom and knowledge that is of the letter Mm spirit.
