An infinitesimal point or Neutral Center where sympathetic forces meet in concord.
Also a state or condition of Love, entanglement or concordance (unison) between sympathetic oscillation or sympathetic vibration.
"I have been repeatedly urged to repeat my disintegrations of quartz rock, but it has been utterly out of my power to do so. The mechanical device with which I conducted those experiments was destroyed at the time of the proceedings against me. Its graduation occupied over four years, after which it was operated successfully. It has been originally constructed as an instrument for overcoming gravity, a perfect, graduated scale of that device was accurately registered, a copy of which I kept, I have since built three successive disintegrators set up from that scale, but they did not operate. This peculiar feature remained a paradox to me until I had solved the conditions governing the chords of multiple masses, when this problem ceased to be paradoxical in its character. As I have said, there are no two compound aggregated forms of visible matter that are, or ever can be, so duplicated as to show pure, sympathetic concordance one to the other. Hence the necessity of my system of graduation, and of a compound device that will enable anyone to correct the variations that exist in compound molecular structures, or in other words to graduate such, so as to bring them to a successful operation." [Keely] [Snell Manuscript - The Book, MINERAL DISINTEGRATION, page 7]
"It [the sphere] is now in condition to denote the sympathetic concordance between living physical organisms, or the receptive transmittive concordance necessary to induce rotation."'' [from 19.02 - Theory of the Induction of Sympathetic Chords to Excite Rotation]
[underline added; this sentence shows the connection to people as we've seen in Atlin, Keely calls sympathetic concordance and is "necessary" to induce rotation]
