Is it a depiction of the Eternal Swan from the Secret Doctrine?
"It is the ONE LIFE, eternal, invisible, yet Omnipresent, without beginning or end, yet periodical in its regular manifestations, between which periods reigns the dark mystery of non-Being; unconscious, yet absolute Consciousness; unrealisable, yet the one self-existing reality; truly, "a chaos to the sense, a Kosmos to the reason." Its one absolute attribute, which is ITSELF, eternal, ceaseless Motion, is called in esoteric parlance the "Great Breath,"* which is the perpetual motion of the universe, in the sense of limitless, ever-present SPACE. That which is motionless cannot be Divine. But then there is nothing in fact and reality absolutely motionless within the universal soul."
