'''Rex and Nada, Bob and Pearl''' are
ascended master youth who lived in the twentieth century in the United States. They received the initiations for the ascension under the auspices of the [[Great Divine Director]], [[Saint Germain]], Lady Master [[Leto]] and the messengers [[Godfre]] and [[Lotus]] in the 1930s.
Their activity is to serve the youth of the world by drawing forth the [[threefold flame]] from the white-fire core of every atom and cell in the being of man. Pearl focuses the purity of the fourth ray (white); Bob, the first ray (blue); Nada, the third ray (pink); and Rex, the second ray (gold).
== Embodiments ==
In their final embodiment, Rex and Nada were the son and daughter of [[Daniel and Nada Rayborn]], also initiates of the [[Brotherhood]], whose
[[ascension]]s preceded those of their children. Bob and Pearl Singleton were brother and sister who were also students of Saint Germain. The Master revealed to them that Rex and Pearl were twin flames and that Bob and Nada were also twin flames.
Rex has been both a teacher of truth and a leader of men in the armies of the great nations of the world, including Greece, France, England and America. He has also served on the fifth ray as a famous scientist in several lives.
