Great White Brotherhood

http://www.crystalinks.com/ascendedmasters.html

Several observations; the brotherhood is seen as a collegiate body basic to the syncretistic teachings of several groups from important spiritual leaders to magical/alchemical personalities and mystics such as Kuthumi. Kuthumi is said to have reincarnated in other lives, yet I cannot help but think this is a similar process to ibbur gilgulim as described elsewhere. Note my video references as well.

The Great White Brotherhood
In some versions of the doctrine, the
ascended masters, as a collegiate body, are the "Great White Brotherhood," white
referring to advanced spirituality rather than race - very much like "Gandalf
the White" after his victory over the Balrog in The Lord of the Rings. In fact,
most early reports of the masters described them as racially Tibetan or Hindi,
not Anglo. Belief in the Brotherhood and the masters is an essential part of the
syncretistic teachings of these several groups. Various important spiritual
leaders such as Jesus, the Prophet Muhammad, the Virgin Mary, and Kuan Yin the
compassionate bodhisattva, take their seats alongside magical or alchemical
personalities like the Count of St. Germain, and other mystic celebrities like
Kuthumi, one of Helena Petrovna Blavatsky's claimed spiritual guides - all of
these leaders have put aside any differences they might have had in their
Earthly careers, and unite instead to improve the spiritual well-being of the
human race.
Reincarnation
Reincarnation is a notable feature of some
groups' teachings about the ascended masters. For example, according to the
Summit Lighthouse the ascended master Kuthumi was also reincarnate as a number
of historically important people, including Pharaoh Thutmose III, the
philosopher Pythagoras, Saint Francis of Assisi, Balthasar the Magus, and Shah
Jahan. Several of the other ascended masters are said to have had equally
distiguished careers in reincarnation.
