We all know and use the Great Invocation, and itf you read further in the Alice bailey books from which it came, it is suggested to use the following as part of the great invocation. Just thought I would put it out there to share.
let the forces of Light bring illumination to mankind.
Let the spirit of Peace be spread abroad,
may men of goodwill everywhere meet in a spirit of Cooperation
may forgiveness on the part of all men be the keynote at this time
let power attend the efforts of the great ones whose pupils we aspire to become
show us the light we seek
give us the strong aid of their compassion and wisdom,
there is a peace that passeth understanding
it abides in the hearts of those who live in the eternal
there is a power that maketh all things new
that power uplifts us
til we stand where the one initiator is invoked
til we see his star shine forth
may the peace and blessings of the holy ones pour forth over the worlds
