Wu-Kuang(1918-2000) was born in a society filled with many different religions. He was interested in religious worship since he was a child. As an adult, he traveled to many places in pursuit of immortal cultivation but was never successful. Eventually, he met a Chan monk who taught him the importance of Buddhist enlightenment. Thus, Wu-Kuang began to study Buddhism. He officially began to study Buddhism when he arrived at Zhuxi temple in 1955. He was tonsured by Master Yen-Ching(1898-1971). After the civil war in Mainland China, Chinese Buddhism came to prominence among Buddhists in Taiwan. Wu-Kuang followed Yen-Ching who was influenced by Tai-Xu (1890-1947) to learn administration, promote education, and reorganize administrative structure at Zhuxi temple. However, Wu-Kuang wanted to study Buddhism more deeply instead, so he went on a retreat for about three months. Then he followed Kung-Ka(1903-1997) who is a Guru of Tibetan Buddhism to learn Tantrism. Afterwards, Wu-Kuang conducted another retreat in Liu-Kuei for three years from 1969 to 1971. He held mantras and studied Tripitaka very well, but some questions couldn’t be answered, so he decided to study abroad in Kōyasan. He was at Kōyasan to study Shingon Esoteric Buddhism in Japan from 1971 to 1972. He received teachings and empowerments of the Kōyasan Shingon-shū Chuin-Ryu Lineage tradition. In 1972, Wu-Kuang returned Taiwan and preached. He began to translate some books and did his writings which includes Shingon Esoteric Buddhism translation and explanations about Shingon-shū thoughts, etc. His teaching followed Shingon-shū scriptures and Kūkai ‘s thoughts. In addition, Wu-Kuang designed his temple by Esoteric Buddhism concept which reflected the influence of Shingon-shū. Wu-Kuang's journey of religious enlightenment which finally gave in to Wu-Kuang’s ultimate study choice presented the achievement of his religious learning and each factor in the era he lived. Moreover, the process reflected Wu-Kuang’s life across WWII in Taiwan. He pursued and chose his further study in religion and led the road to Shingon-shū at last.
