The Memorial of the Presentation of the Blessed Virgin Mary in the Temple recalls – according to the apocryphal gospels, the day on which Mary, while still a child, was brought to the temple in Jerusalem to be offered to God. The Church wants to emphasize not so much the historical event in itself, of which there is no trace in the Gospels, but the total gift that Mary made of herself, by listening: “Blessed are those who hear the Word of God and observe it” (Lk. 11:28). This experience prepared the young girl from Nazareth to become the “temple of the Son of God”.
The celebration of this feast dates back to the 6th century in the East with the dedication of the Basilica of Saint Mary the New built by the Emperor Justinian I near the ruins of the temple in Jerusalem. There is evidence that various monasteries in Italy celebrated the feast in the 9th century. It was not until the 15th century that it was included in the Roman Missal.
This is also the on which the Church celebrates the World Day of Cloistered Life, established by Pope Pius XII in 1953.
PRAYER 
Remember, O most gracious Virgin Mary,
that never was it known
that anyone who fled to thy protection,
implored thy help,
or sought thy intercession,
was left unaided.
Inspired by this confidence
I fly unto thee,
O Virgin of virgins, my Mother.
To thee do I come,
before thee I stand,
sinful and sorrowful.
O Mother of the Word Incarnate,
despise not my petitions,
but in thy mercy hear and answer me.
Amen.
