According to St. Louis de Montfort, the perfect Christian life is acquired through the following manners:
1. An ardent desire
2. Continual prayer
3. Universal mortification
4. A tender and true devotion to the Blessed Virgin Mary
St. Louis de Montfort stresses that among these four means devotion to Mary is the surest, the easiest and the quickest way to the perfect development of the Christ-life in us.
