The Sun's fire here combines with food and raises its quality, which is why food is cooked between 9 and 12 when the Sun is in SE. After SE the rays turn harsher and their heat destroys vitamins and minerals. The Sun is in its youth here, so the zone is called cash flow: the more heat and work, the more money. ESE, SE and SSE together are the cash flow, current and power of the house.
