John Welch (1939-), a Catholic priest of the Carmelite Order, and chair of Carmelite Studies at the Washington Theological Union, in his book, The Carmelite Way, An Ancient Path for Today's Pilgrim, says that St. Teresa of Avila warns that in the third mansion, a person could become too content to leave this place. But the purpose of prayer, Teresa reminds people, is conformity with God's will, not consolations. If one wants to do what God wants, this desire is expressed in the way a person lives his life .
