Energies exchanged by the members of a family, a group, a community, a nation, or a planet.
Group karma is made by individuals when they either move together or fail to move together in concerted action. This karma may be good or bad, positive or negative; that is, individuals acting as a group may misqualify energy or they may qualify it correctly to the glory of God and man. Individuals who have been tied together in the past must reembody as a group in order to work out negative group karma.
Mark L. Prophet and Elizabeth Clare Prophet, The Path to Immortality.
