Romil moved from other monks in a separate cottage for a period of five years and then to Mount Sinai, while Grigorije remained under mentorship of Ilarion.
[1] When Ilarion died Grigorije also moved to Mount Sinai where he became a student of Roman who would later be known as Saint Romil (Romylus) of Ravanica.
[4] After 1375 Grigorije of Gornjak, Romil of Ravanica, Roman and several members of their hesychast brotherhood[5] arrived in Moravian Serbia and put themselves under the protection of Prince Lazar.
They participated in establishing a strong hesyastic colony consisting of Serbian, Bulgarian and Greek monks who came from Mount Sinai.
Grigorije silenced the river to be able to talk with Lazar and since that day Mlava does not make much noise at that place.
