 In 1392 Söflingen Abbey issued a set of laws for the village of Söflingen, an indication of how the idea of rule was changing, away from mere authority of a restricted, local area and towards authority over a wider range of territory.In the 15th century, an echo of the mysticism of the 13th and 14th century became to characterise the spiritual life of the monastery as witnessed by the "Söflinger Briefe" and the "Söflinger Lieder".These letters and songs document an increasing tendency towards spiritualisation and a more poetic approach of piety.
