The Plane of Elemental Mind (B), in its seven sub-divisions, comprises
the states and conditions of a higher form of "elemental" or unseen
entities, playing their part in the general work of the Universe, the
mind and life of which form a part of the scale between the Plane of

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

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
