I used this word to describe the eleventh house because I came across it in the draft of El Maximo Exponente de la Magia's future book on rubbing your dice (geomancy), where the illustrious Professor uses it to describe Albus in the first house. I Imagine it shall be a glorious book and I shall review it on this blog after it gets published.
Speaking of Mr. Farrell, he assigns the Higher Self (Higher Genius, in his ever so Pagan views) to the eleventh house. He likely does that based on ancient Hellenistic attributions of this house, it being the joy of Jupiter and the house of the Good Genius (or Daemon). As a result this house signified good things, especially those of a spiritual nature since it is located above the horizon (Asc-Dsc axis) and thus its associations were with the celestial realm. It is opposite the fifth house, the joy of Venus, which covered good things of an earthly nature.
I will extrapolate a bit on the subject on the Higher Self and its attribution to the eleventh house while risking to provide a major spoiler for the article on the twelfth house (or maybe I'm providing this spoiler on purpose). The way I see it the Higher Self is one's divine spark which in essence is the Supreme Creator, regardless of religious and spiritual views. It would thus be extremely superficial to attribute it to a single house, especially since it transcends the zodiac entirely. You might come across various occultists who advertise classes for getting in touch with certain personal spirits, in way that will greatly praise that spirit, ofttimes calling it transcendental and whatnot. Mind you, that is still a spirit and not your divine spark. I have addressed these things to a degree in my Magical Words.
