centre, the one Being, but looked upon from the side of manifestation,
evolution appears as stated.]

[Footnote 61: Hellenbach, in his book, _Magie der Zahlen_, says
regarding the number seven.

"_The law governing the phenomena on which our knowledge is based
decrees that the vibrations of sound and light regularly increase in
number, that they are grouped in seven columns, and that the vibratory
elements of each column have so close a relation to one another that
not only can it be expressed in figures, but it is even confirmed by
practice in music and chemistry._

"_The fact that this variation and periodicity are governed by the
number seven cannot be disputed; it is not a matter of chance: there
is a cause and we ought to discover it._"

In his table of the elements grouped according to atomic weight,
Mendelejef also acknowledges that the number seven controls what he
calls the _Law of periodical function_. He reaches conclusions similar
to those of Hellenbach.

Dr. Laycock, in his Articles on the _Periodicity of Vital Phenomena_
(_Lancet_) 1842, sums up as follows:--

"_It is, I think, impossible to come to any less general conclusion
than this, that, in animals, changes occur every 3-1/2, 7, 14, 21 or
28 days, or at some definite period of weeks._"]

[Footnote 63: The size of the causal body varies according to its
development. It has been named _causal_, because it contains within
itself the causes or germs of all the other bodies, with the exception
of the denser part of the physical. We say denser because the physical
body is double: its etheric part belongs to the causal body, its
visible part comes from the parents.]

[Footnote 64: The mental body, which is, as it were, an ephemeral
flower of the causal, is born and developed in each incarnation,
disintegrating after the _devachanic_ (heavenly) life.]

[Footnote 65: It moves more or less freely on the astral plane,
according to the development of the astral body. In men of low
development, this body cannot be separated from the physical, under
penalty of a nightmare which brings about a waking condition.]

[Footnote 66: The atoms interpenetrate in consequence of their
differences of tenuity.]

human to the superhuman state and ascends unceas
