Kings bought off priests with land and adornments. Together, they drained the shady ponds and replaced them with fish tanks. The walls of the tank were constructed of ignorance and superstition, held together with fear. After the tanks were in place, nobody talked much about soul anymore. Instead, they talked about spirit.
Soul is hot and heavy.
Spirit is cool abstract and detached. Soul is connected to the earth and its waters. Spirit is connected to the sky and its gasses. Out of the gasses springs fire. It has been observed that the logical extension of politics is war.
