"If thou considerest thyself as having peace from the assault of the affections, before thou hast entered the town of humility, do not trust this. There is some ambush prepared for thee. Expect, after this peace, great trouble from them. While passing along all the apartments of virtues, thou wilt not find rest from thy tribulations nor relief from thy persecutors, till thy course will have reached the apartment of humility."
- Saint Isaac the Syrian
