Rosicrucianism in the context of "Esotericism in Germany and Austria"

Robert Fludd, also known as Robertus de Fluctibus (17 January 1574 – 8 September 1637), was a prominent English Paracelsian physician with both scientific and occult interests. He is remembered as an astrologer, mathematician, cosmologist, Qabalist, and Rosicrucian.

Fludd is best known for his compilations in occult philosophy. He had a celebrated exchange of views with Johannes Kepler concerning the scientific and hermetic approaches to knowledge.

Heinrich Khunrath (c. 1560 – 9 September 1605), or Dr. Henricus Khunrath as he was also called, was a German physician, hermetic philosopher, and alchemist. Frances Yates considered him to be a link between the philosophy of John Dee and Rosicrucianism. His name, in the spelling "Henricus Künraht" was used as a pseudonym for the 1670 publisher of the Tractatus Theologico-Politicus of Baruch Spinoza.

The astral plane, also called the astral realm, or the astral world, or the soul realm, or the spirit realm, is a plane of existence postulated by classical, medieval, oriental, esoteric, and New Age philosophies and mystery religions. It is the world of the celestial spheres, crossed by the soul in its astral body on the way to being born and after death, and is generally believed to be populated by angels, spirits, or other immaterial beings. In the late 19th and early 20th century, the term was popularised by Theosophy and neo-Rosicrucianism.

Another view holds that the astral plane or world, rather than being some kind of boundary area crossed by the soul, is the entirety of spirit existence or spirit worlds to which those who die on Earth go, and where they live out their non-physical lives. It is understood by adherents that all consciousness resides in the astral plane. Some writers conflate this realm with heaven or paradise or union with God itself, while others do not. Paramahansa Yogananda wrote in Autobiography of a Yogi (1946), "The astral universe ... is hundreds of times larger than the material universe ... [with] many astral planets, teeming with astral beings."

The Hermetic Order of the Golden Dawn (Latin: Ordo Hermeticus Aurorae Aureae), more commonly the Golden Dawn (Aurora Aurea), was a secret society from the Western esoteric tradition, that was heavily based on Rosicrucianism and inspired by Freemasonry, chiefly devoted to the study and practice of occult Hermeticism and metaphysics during the late 19th and early 20th centuries. Known as a magical order, the Hermetic Order of the Golden Dawn was active in Great Britain and focused its practices on theurgy and spiritual development. Many present-day concepts of ritual and magic that are at the centre of contemporary traditions, such as Wicca and Thelema, were inspired by the Golden Dawn, which became one of the largest single influences on 20th-century Western occultism.

The three founders, William Robert Woodman, William Wynn Westcott, and Samuel Liddell Mathers, were Freemasons and members of the Societas Rosicruciana in Anglia. Westcott appears to have been the initial driving force behind the establishment of the Golden Dawn. Hence the Golden Dawn system was based on hierarchy and initiation, similar to Masonic lodges. While the grade structure was based on the SRIA, women were admitted on an equal basis with men.

Johannes Valentinus Andreae (17 August 1586 – 27 June 1654), also known as Johannes Valentinus Andreä or Johann Valentin Andreae, was a German theologian, who claimed to be the author of an ancient text known as the Chymische Hochzeit Christiani Rosencreutz anno 1459 (published in 1616, Strasbourg; in English Chymical Wedding of Christian Rosenkreutz in 1459). This became one of the three founding works of Rosicrucianism, which was both a legend and a fashionable cultural phenomenon across Europe in this period.

Andreae was a prominent member of the Protestant utopian movement which began in Germany and spread across northern Europe and into Britain under the mentorship of Samuel Hartlib and John Amos Comenius. The focus of this movement was the need for education and the encouragement of sciences as the key to national prosperity. But like many vaguely-religious Renaissance movements at this time, the scientific ideas being promoted were often tinged with hermeticism, occultism and neo-Platonic concepts. The threats of heresy charges posed by rigid religious authorities (Protestant and Catholic) and a scholastic intellectual climate often forced these activists to hide behind fictional secret societies and write anonymously in support of their ideas, while claiming access to "secret ancient wisdom".

The astral body is a subtle body posited by many philosophers, intermediate between the intelligent soul and the mental body, composed of a subtle material. In many recensions the concept ultimately derives from the philosophy of Plato though the same or similar ideas have existed all over the world well before Plato's time: it is related to an astral plane, which consists of the planetary heavens of astrology. The term was adopted by nineteenth-century Theosophists and neo-Rosicrucians.

The idea is rooted in common worldwide religious accounts of the afterlife in which the soul's journey or "ascent" is described in such terms as "an ecstatic.., mystical or out-of body experience, wherein the spiritual traveller leaves the physical body and travels in his/her subtle body (or dreambody or astral body) into 'higher' realms". Hence "the "many kinds of 'heavens', 'hells', and purgatorial existences believed in by followers of innumerable religions" may also be understood as astral phenomena, as may the various "phenomena of the séance room". The phenomenon of apparitional experience is therefore related, as is made explicit in Cicero's Dream of Scipio.
