Monastic Foundation on Mount Kyminas
After withdrawing to Bithynia, Michael founded a lavra under the direction of the elder John Heladites and was subsequently ordained to the priesthood. Accounts of his ascetic practice describe him spending five weekdays each week in solitary prayer within a cave.
He extended monastic settlement across Mount Kyminas, in the region of present-day Bursa Province, establishing further communities including a monastery at Dry Lake. He is remembered as the abbot of the lavra at Mount Kyminas, a Byzantine monastic center that remained active until monks ceased living there by the Ottoman period. The exact location of the mountain, somewhat north of Bursa, is no longer certain.
