According to R. Allendy, it represents "the role of the Karma 6 in the cosmic unit 10. This role consists in creating a current of evolution (1 + 6 = 7) but towards two opposite directions, so that, by itself, 16 even number, is unable to choose." As a product of 2 x 8, it is the positive evolution leading to the karmic liberation, or the negative evolution leading to an increasingly tight sequence in the cycles of nature.
