In the Ascended Master Teachings, as "Hierarch of the Brotherhood of Truth" in the etheric plane over Crete, Hilarion is said to assist the scientists and spiritual leaders of the world with the "flame of truth" and channels the spiritual energy of what is called in the Ascended Master Teachings the "green ray" or "emerald ray", the 5th of the Seven Rays. It is believed in the Ascended Master Teachings that before the Master Hilarion took over the chohanship of the Fifth Ray, Lord Ling fulfilled that function.
