H.P. Blavatsky on Thomas Vaughan (philosopher)

“The Rosicrucians strove to combine together the most various branches of Occultism, and they soon became renowned for the extreme purity of their lives and their extraordinary powers, as well as for their thorough knowledge... Later... they gave birth to the more modem Theosophists, at whose head was Paracelsus, and to the Alchemists, one of the most celebrated of whom was Thomas Vaughan (seventeenth century), who wrote the most practical things on Occultism under the name of Eugenius Philalethes. I know and can prove that Vaughan was, most positively, "made before he became." p. 43”

“The words “never” and “impossible” ought to be erased from the dictionary of humanity, until the time at least when the great Cabala shall all be solved, and so rejected or accepted. The “Count St. Germain” is, until this very time, a living mystery; and the Rosicrucian Thomas Vaughan another one. p. 45”

“Philalethes, Eugenius. The Rosicrucian name assumed by one Thomas Vaughan, a mediæval English Occultist and Fire Philosopher. He was a great Alchemist.”
