Every great temple has an origin story, and this one begins modestly. Honen, born in 1133 in the province of Mimasaka, in present-day Okayama, climbed Mount Hiei at thirteen and was ordained at fifteen. He later founded the Jodo sect, whose central practice is chanting the nembutsu, the phrase Namu Amida Butsu. Around Higashiyama Yoshimizu, near where the Seishido stands today, he lived in a small thatched hermitage. That humble dwelling is the seed from which Chion-in grew. His teaching was not welcomed by everyone. In 1207, during the Jogen persecution, Honen was exiled to Sanuki province, in present-day Kagawa. Four years later, in 1211, he was pardoned and returned to the capital. His old hermitage had fallen into ruin, so he moved into the nearby Otani Zenbo, which is today's Seishido. He died there on the twenty-fifth day of the first month in 1212, aged 80. After his death, a mausoleum was built beside the Otani Zenbo, but monks from Enryakuji destroyed it in 1227. The story did not end there. In 1234, Honen's disciple Genchi revived the site, and Emperor Shijo bestowed the temple name Kachozan Chion Kyoin Otaniji. From that moment, a hermitage on a hillside began its long journey toward becoming the head temple of a whole school of Buddhism.
