You cannot receive complete divine providence until you shatter your desire for money. Rabbi Nachman of Breslov taught this as a direct spiritual mechanism, not a moral platitude.
The Zohar describes a ruach (רוח), a wind, that descends to cool the burning of the heart (Zohar III:224a). The heart burns with desire. The ruach extinguishes it. This "wind" corresponds to the spirit of generosity that flows through charity: a "generous spirit," as in "He shall cut off the spirit of the noblemen" (Psalms 76:13). Giving tzedakah (צדקה) cools the fever of greed.
When the heart is cooled, it can receive the Levitical song. The Levites sang in the Temple with the joy of those who are content with their portion. Their song corresponded to honest business: "Take up a song and give a timbrel" (Psalms 81:3). The give-and-take of commerce, conducted with integrity and satisfaction, is itself a form of sacred music.
This is also the inner meaning of the ketoret (קטורת), the incense offered in the Temple. The incense binds the heart's burning with the cooling wind. "Incense makes the heart rejoice" (Proverbs 27:9). It nullifies the curse pronounced upon Adam: "By the sweat of your brow you will eat bread" (Genesis 3:19). The sweat, the anxious labor driven by greed, is replaced by trust.
Rabbi Nachman connects this to the revelation of the Mashiach. When the desire for money is finally eliminated, the Messiah is revealed: "On that day, man will throw off his idols of silver and his idols of gold" (Isaiah 2:20). As long as money-worship persists, there is burning anger in the world. When it is nullified, divine lovingkindness floods in, and with lovingkindness comes daat (דעת), holy knowledge, the foundation upon which the Temple itself is built (Berakhot 33a).
