Ingen was born on December 7, 1592, in Fuqing, Fujian, during China's Ming dynasty. Ingen's father disappeared when he was five. At age 20, while searching for him, Ingen arrived at Mount Putuo off Zhejiang province, where he served tea to monks. At 28, after the death of his mother, he was ordained as a monk at his family temple - Wanfu Temple, Mount Huangbo, Fujian. Ingen's teachers there were Miyun Yuanwu and Feiyin Tongrong. In 1633 he received dharma transmission from the latter, and in 1637 served his first term as abbot. His second term as 33rd abbot of the temple began in 1646 and at this time he is credited with helping Mount Huangbo to develop into a thriving Buddhist centre.
