A vow of silence is a vow to maintain silence. Although it is commonly associated with monasticism, no major monastic order takes a vow of silence. Even the most fervently silent orders such as the Carthusians have time in their schedule for talking. Recently, the vow of silence has been embraced by some in secular society as means of protest or of deepening their spirituality. (Wikipedia)
