This line from the hymn at ad Matutinum defines what this is Feast is about, addressing Jesus Christ, Our Lord:
Ascendis orbes siderum, (Thou hast ascended the orbits of the stars)
May we be given the graces by the mercy of God to follow Him there after our pilgrimage on this Earth is over!
Let us therefore start the novena to the Holy Ghost tomorrow to help us on the way!
For the text of the novena, go to the ”Devotions “ page and look for “12. Holy Ghost Novena”
