Money is simply a symbol for mana. Mana can be defined as spiritual authority. Wealth can also generate mana but because everything is a reflection, the reverse is true as well. This blessing also has a positive effect on you, as do all blessings. You can enhance the power of such blessings by performing them in a conscious ritualized fashion.
Human beings are spiritual energy transformers.
Since money is simply a symbol for spiritual authority, one can amplify money by amplifying spiritual energy. Spiritual energy, like electrical energy, is best amplified when it is flowing. An electrical transformer works by amplifying the flow of energy. We can do the same with spiritual energy. We are meant to give and to receive.
