This study is aimed at two purposes. Firstly, to provide a basis for Buddhist counseling for ego growth and interpersonal relationship improvement of the Buddhist lay believers through an objective analysis on the structural ego states and interpersonal stroke exchanges among lay Buddhist believers by using Transactional Analysis(TA) methods. Secondly, to lay out a foundation for TA training program module which can be applied to the Buddhist counseling field by categories of their general characteristics. In order to conduct this research, questionnaires to check ego-grams and stroke exchanges among the lay Buddhist believers were handed out to approximately 700 Buddhist believers across the country for a period of two months from August to September, 2006. A total of 428 solid responses were collected and analyzed their respective ego states and stroke exchanges along with the interrelationships of the two factors. The analysis of the respondents\'s ego states and stroke exchanges has resulted in six significant findings as follows: 1. The Buddhist lay believers showed a structure of their ego states of leading “Adult (A)” ego with deficient “Child (C)” ego. 2. The functional analysis of their ego states showed a pattern of leading “Nurturing Parent (NP)” with deficient “Free Child (FC)”. 3. The result of functional analysis by gender showed that male has a leading NP with deficient “Adapted Child (AC)”, while female has a leading NP with deficient “Free Child (FC)”. 4. According their goals for Buddhist faith, those believers stating it for “self-reflection and meditation” have showed high points of all ego levels except the Adapted Child, while those believers stating their faith goal for “change and healing sufferings and pains” have showed low points of all ego states except Adapted Child 5. Adult (A) and Nurturing Parent (NP) showed a high level of co-relationship with mutual exchanges of positive strokes among them, and for inter-personal stroke exchanges, they exchanged positive strokes more than negative strokes. 6. The co-relationship analysis between functional ego states and stroke exchanges showed that NP had highly related functions between them along with the positive strokes which I give to others (r=.523) and the positive strokes which I receive from others (r=.714). Adult (A) showed high emotional relationship with positive strokes which I receive from others (r=.586). On the basis of the above listed analytical results, the clergy leaders can further develop transaction analysis (TA) training programs for the lay Buddhist believers and TA methods can be used for faith training and meditation.
