The quality of every substance depends upon its vibrations, but so does
the quality of all thought and action. Quality is only one mode of
action; the action of developing, the desire to make this or that, and do
this or that, and the stuff we make are alike due to the nature and
characteristics of vibrations.
I want to connect the actual manufacture of the things a chicken makes
inside an egg with the desire and memory of the chickens, so as to show
that one and the same set of vibrations at once change the universal
substratum into the particular phase of it required and awaken a
consciousness of, and a memory of and a desire towards, this particular
phase on the part of the molecules which are being vibrated into it. So,
for example, that a set of vibrations shall at once turn plain white and
yolk of egg into the feathers, blood and bones of a chicken and, at the
same time, make the mind of the embryo to be such or such as it is.
