is only the one rate of vibration, and only one type of
mental matter will be strongly affected. The mental
body is composed of matter of several degrees of density,
which we commonly arrange in classes according to the
sub-planes. Of each of these we have many sub-divisions,
and if we typify these by drawing horizontal lines to*
indicate the different degrees of density, there is another
arrangement which we might symbolise by drawing
perpendicular lines at right angles to the others, to denote
types which differ in quality as well as in density. There
are thus many varieties of this mental matter, and it is.
found that each one of these has its own especial and
appropriate rate of vibration, to which it seems most
accustomed, so that it very readily responds to it, and
tends to return to it as soon as possible when it has been
