Notes
This chapter describes morale-building rituals based on Five Phases (五行) correspondences: East/blue/8/chicken, South/red/7/dog, West/white/9/sheep, North/black/6/pig. While the Mohists are often characterized as rationalists who opposed superstition, this chapter shows they pragmatically incorporated ritual practices that served military morale and organizational purposes.
