St. John Paul II used this prayer to ask for Our Lady's mantle to be spread over all the people of Ukraine.
When St. John Paul II visited Ukraine in 2001, he began his apostolic pilgrimage with a prayer to Our Lady of Zarvaniza, asking for her intercession over all of Ukraine.
He prayed the prayer at the Greek-Catholic Church of St. Nicholas in Kyiv, asking for the icon to be brought there for the occasion.
Here is the prayer in which he invoked Our Lady's help in covering Ukraine in her mantle.
