a person recorded in the reactive mind of the preclear about whom the preclear makes the reactivecomputation that this person is necessary to the preclear's survival. An ally is an individual who cooperates with, supports and helps another for a common object; a supporter, a friend. In Dianetics, it basically means someone who protects a person who is in a weak state and becomes a very strong influence over the person. The weaker person, such as a child, even partakes of the characteristics of the ally so that one may find that a person who has, for instance, a bad leg, has it because a protector or ally in his youth had a bad leg. The word is from French and Latin and means to bind together. —9th ACC Volume 2 Approved Glossary
