"The First Axiom is of interest to the auditor in his work because with it he can clearly establish whether or not he is confronting a rational reaction. The seven year-old girl who shudders because a man kisses her is not computing; she is reacting to an engram since at seven she should see nothing wrong in a kiss, not even a passionate one. There must have been an earlier experience, possibly prenatal, which made men or kissing very bad."
