May the cross of the Son of God,
which is mightier than all the hosts of Satan
and more glorious than all the hosts of heaven,
abide with you in your going out and your coming in.
By day and night, at morning and at evening,
at all times and in all places,
may it protect and defend you.

From the wrath of evildoers,
from the assaults of evil spirits,
from foes visible and invisible,
from the snares of the devil,
from all passions that beguile the soul and body:
may it guard, protect and deliver you.
Amen.

(A prayer from India of unknown origin, often said before sleep, and incorporated into some of the liturgies of the Church of South India. We use it at my church, All Souls’ Anglican, as a benediction at the conclusion of the Eucharist.)
