Seraphim of Sarov

Seraphim of Sarov (1754–1833) was a Russian Orthodox monk and hesychast widely regarded as the most beloved saint in the Russian Orthodox tradition. Born Prokhor Isidorovich Moshnin in Kursk, he made a formative pilgrimage to the Kiev Caves Monastery around 1776, where the elder Dosifei directed him toward Sarov. He entered the Sarov Monastery in 1778 and spent decades in extreme ascetic practice, including a legendary thousand-day vigil of prayer on a rock in the forest. His spiritual counsel attracted thousands of pilgrims in his later years, and his recorded conversation with the landowner Nikolai Motovilov on the acquisition of the Holy Spirit became a foundational text of Orthodox pneumatology. He was canonized by the Russian Orthodox Church in 1903 and remains a defining figure of the hesychast and philokalic revival in modern Orthodoxy.
