Venerable Cosmas of Yakhrom
Saint Cosmas of Yakhrom was the servant of a certain Boyar, whom he comforted during his long illness by reading to him from books. And so, travelling from town to town, they happened to stop at the Yakhrom River. Exhausted by their long journey, they fell into a sound sleep. Suddenly, Cosmas was awakened by a vision of extraordinary light. In a tree, Cosmas saw an icon of the Dormition of the Most Holy Theotokos, and he heard a mysterious voice say: "Pay attention, Cosmas, and understand the words of life. Lead a God-pleasing life and seek the joy of the righteous, so that you may receive eternal blessings.”
The voice also commanded him to become a monk and to build a monastery.
Reverently, he took the Icon of the Mother of God and brought it to his sick master. As soon as it was placed on the old man, he was healed of his infirmity. When his term of servitude expired, Saint Cosmas went to the Kiev Caves Lavra. After giving the Icon to the brethren, he was tonsured in that Monastery. After he was tonsured, he astonished even experienced monks by his asceticism. The Saint contested there for many years, and then he had a vision of an Angel telling him to leave the Lavra and to take with him the Icon of the Mother of God which had appeared to him.
He asked the monks for the Icon, and left Kiev, arriving at the place where the wonderworking Icon had appeared to him. There, with the help of some pious donors, he built a temple dedicated to the Dormition of the Mother of God. He remained at the church, engaging in various monastic struggles which he had imposed on himself. Disciples began to gather around the Saint, a Monastery was established, and Saint Cosmas was chosen as its Igoumen. During this time, word of his ascetic struggles even reached the ears of the Great Prince.
Saint Cosmas reposed at an advanced age on February 18, 1492, and was buried in the Monastery which he founded. He is also commemorated on October 14, the Feast of the Yakhrom Icon of the Mother of God.1
1 Many sources indicate that it was an icon of the Dormition of the Most Holy Theotokos which appeared to Saint Cosmas, but only a reputed copy of the Icon has been preserved, which depicts the Mother of God according to the "Tenderness" category of Russian icons.
