Martinez tells is that the Holy Spirit does not remain idle; He takes possession of the soul and then his influence extends to our whole being as the Spirit works for our transformation.
"The Holy Spirit lives in the center of the soul, in that profound region of the will where he himself has diffused charity. From that center he pours himself our, so to speak, over the whole person." The Sanctifier p. 17.
We know that when the Spirit is present, the entire Blessed Trinity is present. However, it is good to take time both before and after Pentecost to realize all the Spirit does for us and to spend time thanking for the many gifts the Spirit gives us. I guess I should be doing this every day of the year!
