Learn to let your intuition-gut instinct-tell you when the food, the relationship, the job isn't good for you (and conversely, when what you're doing is just right).
After having stopped the lower activities of the mind, it must be made receptive; and, instead of weaving all kinds of empty and idle thoughts, the mind should receive intuitions from above.
Whether we had a (good) moral intuition more developed, we would be as much morally disgusted by the rapacity of those who try to benefit from, and monopolize (or secure or corner), having no consideration (regardless or irrespective of) for others ("autrui", Fr.), than we physically are by a sickening (or nauseating) smell.
Proverbs are the literature of reason, or the statements of absolute truth, without qualification. Like the sacred books of each nation, they are the sanctuary of its intuitions.
For whereas the mind works in possibilities, the intuitions work in actualities, and what you intuitively desire, that is possible to you. Whereas what you mentally or "consciously" desire is nine times out of ten impossible; hitch your wagon to a star, or you will just stay where you are.
There are many virtues in books, but the essential value is the adding of knowledge to our stock by the record of new facts, and, better, by the record of intuitions which distribute facts, and are the formulas which supersede all histories.
