"Gender is in everything; everything has its Masculine and Feminine Principles; Gender manifests on all planes."—The Kybalion.
The great Seventh Hermetic Principle—the Principle of Gender—embodies the truth that there is Gender manifested in everything—that the Masculine and Feminine principles are ever present and active in all phases of phenomena, on each and every plane of life. At this point we think it well to call your attention to the fact that Gender, in its Hermetic sense, and Sex in the ordinarily accepted use of the term, are not the same.
The word "Gender" is derived from the Latin root meaning "to beget; to procreate; to generate; to create; to produce."
