When researchers perform studies on brainwaves regarding to the initial stages of Buddhist meditation, they tend to ignore the exterior disturbance factors from outside environments. The motive of this research is to make up these discrepancies and the purpose of this research is to try to construct a complete scientific theoretical model for researches of this sort. The theme of this research is “Measurement of anti- exterior disturbance ability for different meditation's engagement positions with brainwave signal”. This research aims to compare how the participants’ brainwaves and balance levels are interfered by exterior disturbance during the initial stage of meditation. Different meditation techniques where the meditators are asked to focus on different objects during meditation are compared. Quantitative analysis, target analysis, structural equation model (SEM) analysis are used for the experiment. LInear Structural ReLation model (LISREL) are used as the analytical tool. The conceptual structure is based on the Buddhist concepts of Hetu, Paticca and Phala. The 4 variables are objects of observation, brainwaves, balance level, exterior disturbances and 19 factors. As the analysis shows, the balance level is affected by different exterior disturbance factors directly or indirectly during the initial stage of meditation.Meanwhile it also shows that the balance level of experienced meditators is higher than people with no meditation experience. For experienced meditators the balance level increases as the duration of meditation increases, as well as the level of concentration. In conclusion, various disturbance factors have different levels of impact in the initial stage of meditation. The brainwaves reveal that the meditators experience different levels of sloth and torpor or agitation during the initial stage of meditation where they are not fully in the concentrated stage and their body and mind are still adjusting.The result of the analysis shows that people who have more experience in meditation has higher levels of balance in all levels of consciousness despite their levels of meditation in the initial stage. Given the relevant factors and verification, the conceptual architectural model used in this research appears to be a valid theoretical model for doing experimental study. The accuracy of the analysis is to be further examined with more experiments.
