Jesus has two different ways to present His departure during the last supper in the Gospel of Saint John. He speaks of the mansions or places of the Father and then speaks about how it is good for Him to leave so that the Holy Spirit can come. There is a separation from Christ that is not due to sin, it is due to His own initiative and in order to strengthen our hearts. There is at the same time a leaving of Christ and a coming of the Holy Spirit. If we allow Christ to leave He prepares a place for us in the bosom of the Father. This place in the Bosom of the Father we begin to inhabit already by the new presence of the Holy Spirit.
