49:5.25
When the intellectual and ethical progress of a human race has reached the limits of evolutionary development, there comes an Avonal Son of Paradise on a magisterial mission; and later on, when the spiritual status of such a world is nearing its limit of natural attainment, the planet is visited by a Paradise bestowal Son. The chief mission of a bestowal Son is to establish the planetary status, release the Spirit of Truth for planetary function, and thus effect the universal coming of the Thought Adjusters.
