At the very outset of his Rule for monasteries, Saint Benedict appeals to the innate desire for JOY present in every heart:

Is there anyone who yearns for life and desires to see good days? (Prologue to the Rule of Saint Benedict, RB prol.)
But true joy is a CHALLENGE: it can blossom only in the soil of self-forgetfulness and self-giving to love, especially to the only LOVE than can completely fill the human heart. To the unfathomable love of God for us—

God so loved the world (each one of us) that He gave His only Son (Jn 3:16)—
all Christians should respond with Saint Paul:

My life in this body is a life of faith in the Son of God who loved me and gave Himself for me (Gal 2:20).
Monks and nuns are Christians who want to live their Christian lives in a radical way:

Prefer nothing to the love of Christ (RB 4).
Hence they strive to imitate CHRIST as closely as possible:

Let us walk in His paths by the guidance of the Gospel (RB prol.).
Long before the little book entitled The Imitation of Christ, the RULE OF SAINT BENEDICT was already a handbook for the imitation of Christ.
By its very name, the Monastery of the Immaculate Heart of Mary happily emphasizes the ideal place for this imitation of and transformation into Christ: the HEART of the MOTHER where the Heart of Christ was formed.
