Halakhah su Salmi 119:20

It is well-known and famous among us - the people that accepted the commandments - that there are seventy faces to the Torah. And in each one of them, there are many great and numerous roots, and to each and every root, [is there] branches - each one supports a great cluster of fruits that are pleasant for hearts to ponder. Each day they put out a flower for those that are constant over them - flowers of wisdom and good reasoning. The depth of its wisdom enlightens the eyes, [it] is broad and surrounding, to the point that a man does not have the power to grasp its end; as the wise king testified (Ecclesiastes 7:23), "I said that I would fathom it, but it is far from me." And with all of this, the hands of the one who is involved with it should not tire, for whether he eats little or much, it is all sweet. And if there are many whose hand will not reach the fruit to take it, let them take the leaves for themselves as medication. And I - with the knowledge of its great value and enormous depth and that 'it is a wonder and sublime for me' - have opened my mouth to speak about it. And I will rely upon what my teachers have taught me (Avodah Zarah 19a), "Let a person recite (ligris), and even though he does not know what he said, as it is stated (Psalms 119:20), 'My soul is crushed (garsah) for desire.'"
