Acts of charity of the persons who practice call Avalokitesvara Guan Yin's name one million times are very great and they get to develop their ability about Buddhism after calling Avalokitesvara Guan Yin's name one million times. The religious group of Tiantai Buddhism held one million Buddhist services of devotion to Avalokitesvara Bodhisattva targeting believers in the temples all over the country before the 100th birthday of Supreme Patriarch Sangwol Wongak who left the intention of 'Practice asceticism through the one million Buddhist services of devotion to Avalokitesvara Bodhisattva' when he lived.

And it was smoothly returned in 2011 when it was the 100th birthday of Supreme Patriarch Sangwol Wongak. The Tiantai Buddhists who participated in the one million Buddhist services by honoring its wish devoted themselves for Avalokitesvara Bodhisattva for hours per day. If you chant Avalokitesvara Guan Yin with an average of 5 to 6 hours per day for 100 days, you get fill one million Buddhist services

Incantations of Avalokitesvara Bodhisattva presented by Supreme Patriarch Sangwol Wongak succeeded to Chinese Tiantai Buddhism and Korean Tiantai Buddhism's unique asceticism method.
