Grant, we beseech thee, Almighty God, that like as we do believe thy only-begotten Son our Lord Jesus Christ to have ascended into the heavens; so we may in heart and mind thither ascend, and with him continually dwell; who liveth and reigneth with thee and the Holy Spirit, one God, world without end.  Amen.

This collect is not only beautiful; understanding what it is saying is critical to the spiritual life.  It is a wonderful prayer not only to pray but to meditate upon.
