For many people the study of esoteric wisdom may be no more than the "salt," or that which gives flavor to life and knowledge.
Whatever is grasped, even without mental understanding, goes much deeper than can be recognized.
It works on the soul.
Like music or art, where the communication is chiefly emotional, there is something transmitted that is of the quality of light.
One "knows" without being able to explain what it is that has been learned.
–Rabbi Adin Steinsaltz
