Certain chemical combinations produce nauseous gases. The human body is a laboratory in which chemical changes are constantly going on. The changes produced by sex-functioning are greater than anything which the experimental chemist has ever discovered in nature.

It is a fact well known to the pathologist that an unwilling wife, however faithful she may be, if forced into the sexual act, may present her husband with a well-defined case of genital disease; nor is this at all strange when we consider the now well-recognized fact that anger, fear, revenge, avarice, and all the destructive thought-forces produce poisons in the secretions of the body.

In Rosicrucian literature, we have the story of "the Chymical Marriage of Christian Rosy Cross," which is, when read with the key to its esoteric meaning, a story of the chemistry of marriage between the sexes. Indeed, the whole story of the secret doctrines of the Rosicrucians, is the story of the sexes, and the "secret of secrets," which was so zealously guarded by the Hermetics and the Rosicrucians and other secret societies, is the secret of the spiritual union of the male and the female principles throughout nature and culminating in man and woman, conferring upon them immortal life through the perfect balance of sex.

It has been said that women were not admitted to the Brotherhood of the Rosicrucians, but this is not true, as there is plenty of evidence to prove.

Owing to the enmity of the established Church toward any exaltation of the sex-relation, and particularly toward the veneration of woman, it became necessary for those who sought to keep alive the fires of Esoteric Wisdom to surround themselves with the most rigid secrecy; in consequence of this, the story of the sexes, constituting the very heart and center of Hermetic philosophy, has been told in allegory, unintelligible unless one has the inner sight or has been initiated into the secret code.

In the sixteenth and seventeenth centuries, the Church had so far succeeded in undermining the work of the Hermetics, that women were excluded from the Brotherhood, and the apparent sole purpose of the secret order was the search for metallic transmutation. Side by side with this convincing evidence that the esoteric meaning of the symbols has been perverted, we find their allegorical phraseology intermixed with frequent allusions to passages from the Scripture and to the Virgin Mary, proving conclusively that the Church, then in the zenith of its power, had confiscated the archives of the secret order, and, either through fear of the influence of their work, or possibly through lack of any adequate comprehension of their wisdom, had employed their symbolism to the further glory of the temporal power of the Church.

This subject will again be dealt with in a chapter devoted to "The Hidden Wisdom," and so we will leave it for the present.

One other great spiritual truth relating to marriage is found in the intimate and constantly recurring association of the turtle-dove with the ceremony of marriage.

The dove is, par excellence, an example of conjugal love. The turtle-dove, more than any other of the dove family, is noted for the fervor of its sexual desires; fidelity to its mate; and for the devotion and diffusion of its love nature. It is well known that if either of a pair of turtle-doves dies, the mate will grieve itself to death. "Like a pair of turtle-doves" is said of a couple who are happily married, and the domestic life of the dove has made the dove a symbol of peace.

Doves have been held sacred in many parts of the world, and figure prominently in religious symbolic architecture and utensils, from ancient times down to the present day. The symbol of the doves flying over the ark of the covenant typifies the spiritual origin of birth, the ark being the primordial egg, from which issued all the forms of life. Let us also remember that they issued in pairs.
