Rabbi Nachman teaches,
To draw G-d’s providence upon ourselves completely, it is necessary to break the appetite for wealth. This is achieved through giving charity. When a person gives money to charity, it cools his urge to acquire. He conducts his business affairs truthfully and honestly and is satisfied with his portion in life, having pleasure and contentment from what G-d has blessed him with. Since he is not desperate to become rich, he is free from the constant struggle to make extra profit. The burden of this struggle is the fulfillment of the curse: “By the sweat of your brow you shall eat bread” (Genesis 3:19 ) . When a person gives charity he is freed from this, and it is accounted to him as if he has brought an offering of incense to G-d.
