All of us have different aspects of our personalities which come to light under different circumstances with different people and at different places. Under the changed place, people and circumstances the same person may behave differently. What makes this variation possible is the EGO STATE from which he/she is operating at the particular time. An EGO STATE can be defined as a state of mind which triggers action at that particular time. Three basic EGO STATES are recognized: Parent ego state Adult ego state and Child ego state.
