“The second attribute of perfection is justice and impartiality. This means to have no regard for one’s own personal benefits and selfish advantages, and to carry out the laws of God without the slightest concern for anything else. It means to see one’s self as only one of the servants of God, the All-Possessing, and except for aspiring to spiritual distinction, never attempting to be singled out from the others. It means to consider the welfare of the community as one’s own. It means, in brief, to regard humanity as a single individual, and one’s own self as a member of that corporeal form, and to know of a certainty that if pain or injury afflicts any member of that body, it must inevitably result in suffering for all the rest.” ~ ‘Abdu’l-Baha
