When you're spending money consciously, you're using it for necessities and that which really brings you a sense of all is well, a sense of true enjoyment. One of the six energies of money is the energy of enjoyment. You have the energy of money, time, creativity, enjoyment, relationship, and physical vitality.
To leak money means that whatever you spend the money on, you don't get a sense of enjoyment out of it. It's just like fog.
