The higher self enters the body and drives out everything that has turned the sacred place into a market. The temple is the body, meant as a house of inner worship, and the moneychangers are the faculties that reduce spiritual worth to gain, weighing the holy in terms of profit.
Overturning their tables is the Christ self clearing the house of that lower trade, and the doves being sold are the finer spiritual powers, offered up for barter and cheapened in the exchange. When the higher self takes possession, the body is swept clean of every faculty that has been selling its sacred life for something less.

Moneychangers: the faculties that reduce spiritual worth to profit, weighing the holy as gain
Doves: the finer spiritual powers, cheapened when they are put up for barter
Tables: the seats of the lower trade, overturned when the higher self clears the house
