The Great Invocation is a World Prayer, an invocation for peace, light and love, that doesn't belong to any religion but to the world.
It's usually used at the end of the work of love of the Rama groups, of sending energy to the world where needed.
Original 1945 Version
by the English Alice A Bailey & the Tibetean Djwhal Khul
The Great Invocation
From the point of Light within the Mind of God
Let light stream forth into the minds of men.
Let Light descend on Earth.
From the point of Love within the Heart of God
Let love stream forth into the hearts of men.
May Christ return to Earth.
From the centre where the Will of God is known
Let purpose guide the little wills of men
The purpose which the Masters know and serve.
From the centre which we call the race of men
Let the Plan of Love and Light work out
And may it seal the door where evil dwells.
Let Light and Love and Power
restore the Plan on Earth.
(so be it and so it is)
