The Novena to the Holy Spirit is a nine-day prayer after the Feast of the Ascension where we pray for the descent of the Holy Spirit in a fresh way in our hearts as he descended upon the followers of Jesus on the day of Pentecost. Jesus instructed his disciples to pray earnestly for the coming of the Holy Spirit, and they did—for nine days, the first novena.
This novena has a daily prayer at the beginning which changes each day, followed be a set of prayers which are repeated every day.
