The Ascended Master* Saint Germain is the Chohan of the Seventh Ray.
(Chohan is a Sanscrit word for 'Lord'. To be a Chohan of one of the Seven rays means, the energy of that ray in Christ and God, flows through that Master to all on earth who are evolving on that particular Path).
The Seventh Ray is the Violet Flame of Freedom, Alchemy and Transmutation.
It corresponds to the Seat-of-the-Soul Chakra

Saint Germain is the Hierarch of the new 2000 year cycle, the Aquarian Age and as the Chohan of the Seventh Ray, he initiates us in Divine Alchemy, Transmutation, Prophecy and the gift of the Working of Miracles.

He maintains several spiritual retreats where we can go to study at night while our body sleeps. One of them being the Rakoczy Retreat in Transylvania - Romania and another one is the Cave of Symbols in the Table Mountains of Wyoming.
The Ascended Master Saint Germain teaches that the highest Alchemy is the transformation of one's human consciousness into the Divinity of the Higher Self. He stands ready to assist all souls in this endeavor. He has also said he would release the technology of the Aquarian Age when the nations shall have put behind them the destructive uses of science and religion to accept the challenge which lies at the heart of both, which is for man to enter his heart and the nucleus of the atom and to harness from both the unlimited spiritual and physical resources for establishing the Golden Age.

Some of his past embodiments: the Emperor over a Golden Age civilization 50,000 years ago, as high priest of the Violet Flame Temple on Atlantis, Samuel, Prophet of the Lord and Judge of the twelve tribes of Israel (c.1050 B.C.), as Merlin the magician who stood beside King Arthur and his Knights of the Round Table, as Roger Bacon (c.1214-1294) scientist, philosopher, monk, alchemist and prophet and as Christopher Columbus (1451-1506).
He was also Francis Bacon (1561-1626) the greatest mind the West has ever produced, known as the father of inductive reasoning - this and his scientific methods are responsible for the age of technology in which we now live. His plan was to educate the common man and he wrote his works not in Latin, but in a language that ordinary men could read and understand. He and some of his followers developed the English language, wrote the Shakespearean plays and translated the Bible. In May 1684, Saint Germain took his ascension. He reappeared afterwards as the Count of St. Germain, the Wonderman of Europe, in the 18th.Century.
