This is the time during which the very first novena of the Church Age was made, when Mary and the Apostles prayed from Christ's Ascension to the Pentecost, a period of nine days (Acts 1-2).
Ninth Day:
Come, O Divine Spirit, fill my heart with Thy heavenly fruits, Thy charity, joy, peace, patience, benignity, goodness, faith, mildness, and temperance, that I may never weary in the service of God, but by continued faithful submission to Thy inspiration, may merit to be united eternally with Thee in the love of the Father and the Son. Amen.
Recite one Our Father, one Hail Mary, and seven Glory Be's
