The Holy Spirit has His own place in the universe, in Mary’s heart. At Mary’s conception, the Holy Spirit took up His residence within her. When she accepted the Father’s invitation, He overshadowed her. On Pentecost, when Jesus sent His Spirit upon the apostles, the Holy Spirit was already living within Mary.
Jesus sent the Holy Spirit, not from heaven but from Mary’s heart. The fire within her became like tongues of fire and rested on all. The apostles shared in the gift which Mary received at her conception.
Whenever the Father and Jesus send the Spirit, they always send Him from Mary’s heart. When this mystery is revealed, all will know that they must enter Mary’s heart.
