The Plane of Elemental Mind (C), in its seven sub-divisions, comprises
those entities or beings, invisible as are all such elemental forms,
which partake of the nature of both animal and human life in a degree
and in certain combinations. The highest forms are semi-human in
intelligence.

The Plane of Human Mind, in its seven sub-divisions, comprises those
manifestations of life and mentality which are common to Man, in his
various grades, degrees, and divisions. In this connection, we wish to
point out the fact that the average man of today occupies but the fourth
sub-division of the Plane of Human Mind, and only the most intelligent
have crossed the borders of the Fifth Sub-Division. It has taken the
race millions of years to reach this stage, and it will take many more
years for the race to move on to the sixth and seventh sub-divisions,
and beyond. But, remember, that there have been races before us which
have passed through these degrees, and then on to higher planes. Our own
race is the fifth (with stragglers from the fourth) which has set foot
upon The Path. And, then there are a few advanced souls of our own race
who have outstripped the masses, and who have passed on to the sixth and
seventh sub-division, and some few being still further on. The man of
the Sixth Sub-Division will be "The Super-Man"; he of the Seventh will
be "The Over-Man."

In our consideration of the Seven Minor Mental Planes, we have merely
referred to the Three Elementary Planes in a general way. We do not wish
to go into this subject in detail in this work, for it does not belong
to this part of the general philosophy and teachings. But we may say
this much, in order to give you a little clearer idea, of the relations
of these planes to the more familiar ones--the Elementary Planes bear
the same relation to the Planes of Mineral, Plant, Animal and Human
Mentality and Life, that the black keys on the piano do to the white
keys. The white keys are sufficient to produce music, but there are
certain scales, melodies, and harmonies, in which the black keys play
their part, and in which their presence is necessary. They are also
necessary as "connecting links" of soul-condition; entity states, etc.,
between the several other planes, certain forms of development being
attained therein--this last fact giving to the reader who can "read
between the lines" a new light upon the processes of Evolution, and a
new key to the secret door of the "lea
