So I say now that all of us who wear this holy habit of Carmel are called to prayer and contemplation. This call explains our origin; we are the descendants of men who felt this call, of those holy fathers on Mount Carmel who in such great solitude and contempt for the world sought this treasure, this precious pearl of contemplation (Cf. Mt 13:46) that we are speaking about.Saint Teresa of Avila
