1 After strivers become members of the Lord of Universe Church, they should follow the five cardinal disciplines, affirm the Twenty Watchwords and use them as their own code of life, beginning with themselves.
2 The divine beings in the nonphysical realm also follow them, as we humans do. After a person has passed on, his spirit reaches the inferno, and he still has to go to the Twenty Watchwords Hall! He still has to use the Twenty Watchwords to cleanse his spirit.
3 Thus, all beings from the human domain, from the underworld, and from the heavenly domain beneath the stratosphere must rely on the power generated from the Twenty Watchwords, in order to cultivate and raise their spirituality. Hence, to follow the Twenty Watchwords is the one and only way to self-cultivation, and is used by beings in the three realms.
