'''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).
