Buddhism has influenced greatly in our lives and culture after being handed down. Buddhist temple is the place for buddhism enforcement and meditation and a complete religious form that made Buddha land, Buddha' s world of Vairocana revive in this world and understanding the teachings by Buddha. Temple has been built as flatland or Mountainous district Temple with the aim of propagation and performance. It perceived the importance of structure to supplement the weather conditions from the geographical features. This had influenced Buddhism and Geomancy. The continuity and rise and fall of mountain temple differs by structure and shape. There was the need to choose location in the aspect of yang in order to improve human's life quality and fulfill recreation by using geographical energy.
Geomancy is a study which understands the variational theorem by the direction or the flow of the effect of water made from revivification of the land's spirit and solar's energy and wind transforming into bio energy as nature's essential order. It is a term coined from the idiom Jangpungduksu, meaning preventing wind and gaining water's energy, the fundamental theory of Geomancy. The Yang energy is a study which takes place of birth where virtue from the air and energy from the earth are combined. With geographical features which emphasizes the range, acidemia and field of the mountain as the foundation, the mutual union such as Juse theory, Gukse theory and Suse theory are created.
Tongdo-Sa Temple was built in Silla year 646 by Jajangyeulsa and contains sari(Buddha's skull) and gasa(Buddha's cloth). Also, it is a temple that enshrines the whole body sari and is one of the five temples enshrining Buddha's sari.
When Jajangyeulsa first decided the location, the substructure was a big harming region in Geomancy due to the amount of the water from large superstructure.
In order to solve this problem, he cultivated the mountainous territory and created farmland and made reservoir water facilities to save water. Due to the cultivation, the harm decreased to great amount by securing the space to keep fresh water and the Sangrojun Area in Tongdo temple controlled the water by collecting it to one place. When comparing it to a kettle, it is the nose, the entrance. This is the place where the temple was built. It was controlled by changing the waterway where the water comes down. Next, the Jungrojun was built and then Harojun was built in order.
Tongdo temple was built during the transformation from flatland temple to mountain temple. There are 17 small temples near Tongdo temple. They are located in key valley and they were built in the most important spot. Due to these happenings, I believe it influenced the monks which helped in developing Tondgo temple.
Hwangnyongsa Temple in Kyungju has preserved sari at the same time and combined Buddha land theory with Silla's Buddhism and influenced on unifying the three countries. By using the power of buddhism, they let the people experience the power of Buddha and has used it as a ruling method for the district. In the downstream region of Tongdo temple there is a village called Mulgum. As can be inferred from the name, it is a prohibited area. Next to it there is the Nakdong river and across from here is the Gumgwan Gaya. This is the region granted to Gaya influence, Kimyusin family after Gaya merger. With the excess national tax, the problems are still remaining to the people in the area. I believe true development can be made when proper control is performed.
