"It seems that when men generate a large number of malignant Thought-forms of a destructive character, and when these congregate in huge masses on the Astral Plane, their energy may be, and is, precipitated on the physical plane, stirring up wars, revolutions, and social disturbances and upheavals of every kind, falling as collective Karma on their progenitors and effecting widespread ruin."
