The physical and mental creation may be considered as one personality. Man forms the Grand Man, sometimes known as Adam. This includes all the Life beneath the mind-mesh. The world above the mind-mesh, called by the Sufis Djabrut, is identical with Eden. Adam expelled from Eden is all of the humanity functioning in the worlds of limitation. Whatever any personality does effects this whole kingdom of man as well as himself.
Of course each man's actions effect himself most of all. His every word, speech and thought strike the dome of Malakut and fall back again to their natural place. This return of energy not only touches the individual but touches the whole of humanity. Thus if a person spreads germs or disease, every man might be liable. This show the inclusive nature of Karma. Likewise kindness spreads abroad and the tales of good deeds often bear fruit in faraway places.
