The “Circle of Light” prayer is a very good, spiritually universal, nondenominational protection prayer. Sometimes, this prayer is recited after lighting a blessed (or just a normal) candle. The individual, before reciting the prayer, first envisions that he or she is completely surrounded by a strong circle of protective light.
Some alternate versions of the prayer are available (some only recite the first four or five lines), but the majority of them are similar to the following:
The light of God surrounds us (me).
The love of God enfolds us (me).
The power of God protects us (me).
The presence of God watches over us (me).
Wherever we are (I am), God is.
And all is well.
