Eric Bern, the prominent psychologist divides human personality in to three basic structural aspects, namely Parent, Adult, and Child in his transactional analysis. He believes when each aspect plays its own role on a just time, in compliance with the balance and interaction, one's mental health would be shown and a noble healthy man can, in this situation, provide proportion with the help of reasoning and deduction (Adult) between his instinct (Child) and education and training (Parent). Balance disruption of clues between child and parent is a sign of imbalance in the psyche and human behavior; if the adult creates balance between the child and the parent, the image of Perfect Human will be appeared, but if the rough, arrogant and caviler parent dominates the child the one will use the social masks and will seek others' love narcissistically and incompetently and will follow the profit and loss worldly and otherworldly. Masnavi Ma'navi contains several human groups, from every spectrum of behavior and belief that their different psychological and behavioral features have been reflected and scrutinized. So the researcher can accomplish a transactional analysis on heroes of his stories psychoanalytically. The authors, in present essay, analyze the aspects of "Parent" and "Adult" in Masnavi's characters and make their clues highlighted in Mowlavi's description of his characters' behavior.
