Life
By the account of the synaxarion, Cosmas was born toward the end of the eighteenth century into an aristocratic Bulgarian household and grew up proficient in both Greek and Bulgarian. When his parents wished him to marry, he departed his home secretly and set out for Mount Athos.
On the Holy Mountain he entered Zographou, the historically Bulgarian monastery, and took up the life of an anchorite, dedicating himself to ascetic discipline and prayer in seclusion.
