If one is affected by disease and unable to recover, one may become deformed or invalid or, in an extreme case, lose one's life. Likewise, a diseased society will become crippled or degraded, and eventually fall into ruin if the leader of that society is unconscious of the disease or for a long time fails to seek a remedy.
Generally, if a society shows any of the following symptoms, that society is affected by a disease: People are not conscious of their own faults, but always reveal the faults of others. People unduly rely upon others. People are not willing to follow the righteous leader as they are supposed to. The leaders are indifferent to the education of their people, not giving them the right instruction. People are rarely public spirited, seldom encouraging good people and showing no compassion for the weak; they rarely offer profitable things to others, taking them only for themselves, and they do not give consideration to the comfort of others while seeking their own comfort.
To remedy these diseases the people must always reflect upon their own wrongdoings, shed their unreasonably dependant style of living, follow leaders who will give them righteous instruction and educate them by right instruction, and the people must not be egoistic but altruistic. These are the correct cures for a diseased society. As a result of these treatments the society will recover completely from disease, changing into a healthy and peaceful society.
