In effect, then, the bishop commands everyone to banish worldly thoughts and workaday cares and to have their hearts in heaven with the good God. Cyril in his interpretation of the Sursum Corda focused expressly on the idea of heavenly mindedness. Worldly thoughts were to be banished and the heart was to be in heaven where the good God is. At first, after the prayer, you are admonished to lift up your heart. This befits the members of Christ.
Members have a head.

If, therefore, we celebrate the feast of the Ascension of the Lord with due ceremony, with faith, devotion, holiness, and reverence, let us ascend with Him and let us have our hearts lifted up to Him. Moreover, though we ascend, let us not be lifted up.
