Here's a link to the video on AirMaria. The novena prayer is part of the video, which is only about 6 minutes; meditation + prayer(the prayer shows up on screen). I can't embed it cause I cant figure out how to embed their videos without autoplaying them.
Here's the text of the prayer.
Priest: A great sign appeared in heaven: a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars.
People: O Immaculate Virgin, Mother of God and Mother of men, we believe with all the fervor of our faith in Your Triumphal Assumption into heaven, where You are acclaimed as Queen by all the choirs of angels and legion of saints. We unite with them to praise and bless the Lord who has exalted You above all other pure creatures, and to offer You the tribute of our devotion and our love.
From the shadows of this valley of tears, we seek Your heavenly assistance and tender mercy, to comfort our aching hearts and to help in the trials of the Church and of our country. Accept the intentions we offer you in this novena, and be pleased to grant them according to our need and according to the good pleasure of Your Son, for we are confident that in the glory where You reign, You continue Your manifold intercession to bring us celestial gifts. In the glory which you possess in body and soul in heaven is the image and beginning of the Church as it is to be perfected in the world to come. Until the day of the Lord shall come, continue to shine forth on earth as a sign of certain hope and comfort for all your children, O clement, O loving, O sweet Virgin Mary.
Priest: Let us pray. Almighty everlasting God, who assumed to celestial glory the body and soul of your Son’s Mother, the Immaculate Virgin Mary, grant, we beg You, that , being ever intent upon heavenly things, we may merit to share in her glory. We ask through Christ our Lord.
People: Amen.
Priest: Queen assumed into heaven.
People: Pray for us.
