The words are ascetic. Isaac Sirin, Rev.

Creations of St. Isaac Sirin are well acquainted with the Orthodox reader and do not need to be submitted. The Monk Paisiy Svyatogorets, who was very revered by the holy Isaac, wrote to him by the volume of “ascetic words” with his hand: “Avva, give me your pen, so that I emphasize all the words in your book,” that is, he would not only read and fulfill the most all the instructions written in it. What we sincerely wish all who picked up the book of the creations of this greatest ascetic, the secretary and theologian.
