...the work of Christ himself, head and members, and active participation in the liturgy is a participation in the very work of Christ. In the liturgy, the real sacrifice being offered is Christ himself (head) and us (body) continuing his sacrifice for the salvation of his people.

Our "conscious participation" in the liturgy leads to the offering of one's whole self. The offering of the Mass does not belong to the priest alone, and the sacrifice of the Mass is not only bread and wine but the offering of one's whole self.
