To concentrate on their religion.
Not necessarily. Many religions have monks. Monks are people who withdraw from ordinary life to pursue their religious beliefs on a daily basis. So you can have Christian monks, Buddhist monks, Hindu monks, etc. Islam does not have a similar tradition though.
Neither Franciscans or Jesuits are monks.
church men who separated themselves from the world
monk is not a he its a or the monks. monks are the praiser of there god or spirit the monks of the Christan live at the cathedral so do Buddha monks! almost all religions have monks. heres an example of monks and every thing..... praiser>monk>priest.
The Franciscan Order. However, they are not monks, they are friars. Monks live in a monastery and work there, friars live in a convent or friary and work in the "real world."
Because the numbers were not there
In monasteries.
For Christian monks, it depends on the monastic order they've joined. All orders emphasize regular prayer and introspection. Beyond that, some orders are founded to do missionary work, some focus on agriculture, teaching, or other service, some are contemplative orders; that is, they withdraw from the society around them to study and pray. It is my understanding that Buddhist monasteries can be much more flexible in what their members do. All monks must study the dhamma lessons and learn to meditate. This is necessarily a very brief, simplistic answer.
Because it is shaped like that
Monks are not very common in the United States with more residing in European countries in old medieval monasteries. But all around the world, the number of active monks or nuns in the brother/sisterhood is decreasing at an alarming rate.
The collective noun for monks is an abomination of monks (from the older 'an abominable sight of monks').
Some types of monks include Benedictine monks, Franciscan monks, and Trappist monks. Each type of monk belongs to a different religious order with its own set of customs, practices, and rules.
