Djwhal Khul is described within the Theosophical tradition as a Tibetan Master — a human being who has completed the cycle of earthly incarnations and now works from an inner plane to guide humanity's spiritual evolution. He is said to have been a Tibetan monk in his last physical incarnation, and to work closely with the Masters El Morya (First Ray) and Kuthumi (Second Ray), serving as a kind of research assistant and communicator within the Hierarchy — the inner government of the planet.
His name first appears in the Mahatma Letters — the correspondence between the Theosophical Masters and A.P. Sinnett in the 1880s — where he is mentioned as a young chela (disciple) of the Master Kuthumi. By the time of the Alice Bailey transmissions (1919–1949), he had evidently advanced considerably. He describes himself in the Bailey books as a Master of the Fifth Ray (Concrete Knowledge and Science) who has chosen to work as a teacher and communicator rather than focusing on his own further advancement.
DK is notably modest in his self-presentation — repeatedly emphasising that the student should verify his teachings against their own experience rather than accepting them on authority. "I am not a young man, as age is counted, though I am not as old as some of my fellow workers," he writes in the preface to Treatise on Cosmic Fire. He asks to be judged by the quality of the teaching rather than by claims of his identity. This epistemological humility distinguishes him from many channelled sources, which tend to emphasise the authority of their origin.
