(Silver and Gold Aset Temple Cartoushe)
“The lips of the wise are as the doors of a cabinet; no sooner are they opened, but treasures are poured out before you. Like unto trees of gold arranged in beds of silver, are wise sentences uttered in due season.”
Indeed, being loud and rude is spoken against in the teachings because it promotes extroversion and egoism and of course, delusion and mental dullness.
The reverence for the teaching and the teacher is not for the sake of not offending the teaching or the teacher but it offends the spirit within oneself. One wants to have a good relationship so that the teacher may share all that is necessary that an aspirant can receive. When there is rudeness towards the teacher or the neteru, they as if clam up because their words are or may fall on deaf ears. A singular pleasure they have is sharing the teaching so it does not take much to precipitate glorious words; and also it does take something to stop the flow of wisdom but that is not their doing, it is the doing of the aspirant, by their egoism, shyness, rudeness, disrespect of the process, etc. So an aspirant should cultivate ethical conscience, courteousness and reverence but that only after vetting the teaching and the teacher. Then they can choose to humble themselves to the teaching and the teacher and receive the benefits therein.
