...if for no other reason than that it's a great Scrabble word!od \od, ohd\, noun:
a hypothetical force formerly held to pervade all nature and to manifest itself in magnetism, mesmerism, chemical action, etc.
"I studied mind-cure, or metaphysical healing, which strikes at the root of disease; I went into hypnotism, mesmerism, and phreno-magnetism, and the od force—I don't suppose you know about the od which Reichenbach discovered."
-- Edward Eggleston, The Faith Doctor: a Story of New York, 1891
In these experiments, different substances from which the od was supposed to emanate were arranged on a collodion plate.The term od was coined by chemist and philosopher Karl Ludwig von Reichenbach as a name for his hypothetical force. He proposed the name od because he thought a short word starting with a vowel would be more easily combined in compound words.

Though the concept of od is archaic, I would argue that the law of attraction is connected to some old beliefs about it.
