Purpose: This study purports to investigate the effects of Sasimsagwan meditation therapy, one way of Buddhists` ascetic practices conducted to reduce the state anxiety. Method: The subjects of this study were college students, 34 of whom were grouped as experimental group and 35 as control group. The study is designed as the quasi-experimental research before and after the time lag of non-synchronized control group. STAI(State-Trait Anxiety Inventory) created by Spielberger was used as a tool to measure the state anxiety. Result: The experimental group conducting Sasimsagwan meditation therapy showed the decrease in anxiety level by average 7.23 lower than the control group which did not perform any Sasimsagwan meditation. It was also revealed that there is a significant difference of p<.001 between experimental and control groups. Conclusion: It may be concluded that the Sasimsagwan meditation therapy can help bring down the anxiety caused by the threatening perception by letting us take insight on the essence of the fact transcending the language or perception which has usually been used as ultimate means.
