Fu Dashi
Fu Dashi was a Chinese Buddhist layman who lived in Dongyang under the reign of Emperor Wu of Liang during the Northern and Southern Dynasties. In Chinese Buddhist tradition, he is popularly revered alongside Bodhidharma and Baozhi as the "Three Mahāsattvas of the Liang Dynasty".
In traditional Buddhist hagiographies of his life, Fu Dashi is recorded as having overseen the construction of Shuanglin Temple and compiling an early version of the Chinese Buddhist Canon. In the same Canon, he is credited as the author of the "Ode to the Diamond Sūtra", a commentary on the Diamond Sūtra. According to some accounts, such as the “Chronicle of the Buddhas and Patriarchs”, Fu Dashi implied that he was Maitreya Buddha and founded the Maitreya Sect during his lifetime. In addition, he is often credited as the inventor of the Chinese revolving bookcases, or zhuanlunzang that are often found in the Zangjing Ge of Chinese Buddhist monasteries.
Fu Dashi also appears in certain Chan Buddhist gong'ans. One example is case 67 in the Blue Cliff Record, where Fu Dashi is recorded as having been invited to speak by Emperor Wu. According to this account, Fu Dashi stepped up to the lectern, struck it a blow with his staff, and then returned to his seat without speaking a word.
