query: What was the influence of Hesychasm on the development of rock monasteries during the 14th century in Bulgaria?
answer: With the growing influence of Hesychasm during the 14th century, rock monasteries became widespread in Bulgaria.  Monks' dwellings and churches were hewn directly into rocks, with added wooden balconies and stairs (though only the rock cradles remain). These monasteries were primarily built in northeastern Bulgaria.
