Discipline is always one of the core activities of any cultural group or intellectual family. Every organized group strives to harmonize the best way possible the interpretations and visions of its members. This attempt can take manifold forms. It can be realized through compelling documents and constitutions, through singular acts of censorship or positive reinforcement; sometimes It takes the form of more or less explicit admonitions and warnings. This practice of disciplining can be observed in Mendicant Orders, particularly in the Franciscan Order. The first century of the order saw harsh debates between different sensibilities and the concomitant attempt of the ruling bodies of the order to achieve a cultural and spiritual unity through many different practical means. To explore these topics, my proposal is to read one of the treatises by Ugo Panziera (1270 ca - 1330). Ugo Panziera was a Franciscan friar, probably involved in the spiritual secession, and later repression, of the spirituals during the last quarter of XIIIth century. Later, he moved to Constantinople. His work consists in several small treatises of different topics. One of them is dedicated to answering a request, arrived from some young friars, about a peculiar way of praying, probably a specific form of hesicasm. In Panziera's reply we can appreciate several themes. Firstly, the attempt to educate the younger friars regarding their spiritual progress. Secondly, the cautious relationship with a foreign kind of religious experience. Lastly, the concern for the orthodoxy of the Order in the perilous context of missions abroad.
