This powerful Prayer comes from, the book A New Earth, and can be used for any occasion.

“Lord, grant that I may disappear in your eternity
and your immensity;
take my place and dwell within me.
Manifest yourself:
through my intelligence as wisdom,
through my heart as love,
through my will as power,
So that the kingdom of God and his righteousness
may be established on earth.”

Omraam Mikhael Aivanhov
