nation in a form must teach it,
this form is necessary, and is given to it again and again until the
soul has assimilated the experience that form had to supply; when it
has nothing more to learn from the form, on returning to incarnation
it passes into one that is more complex. The soul learns only by
degrees, beginning with the letters of the alphabet of Wisdom, and
gradually passing to more complex matter; thus the stages of evolution
are innumerable and the transition from one to the other
imperceptible; modern science states this fact, though without
explaining it, when she says that "Nature makes no leaps."

The building up of forms is effected by numerous Beings, forming an
uninterrupted chain that descends from the mighty Architect, God, to
the humblest, tiniest, least conscious of the "builders."[58] God, the
universal Spirit, directs evolution, and could accomplish every detail
of it directly; but it is necessary, for their own development, that
the souls, whatever stage they have reached, should work in the whole
of creation, and therein play the part, whether consciously or
unconsciously, that they are fitted to play. Consequently they are
employed at every stage; and, in order to avoid mistakes, their
activity is guided by more advanced souls, themselves the agents of
higher cosmic Entities, right on up to God, the sovereign controller
of the hierarchies. Consequently there are no mistakes--if, indeed,
there are any real ones at all--in Nature, except those that are
compatible with evolution and of which the results are necessary for
the instruction of souls; but the Law is continually correcting them
in order to restore the balance. Such, in general outline, is the
reason for the intervention of beings in the evolutionary process.

So far as man is concerned, the highest of these Beings supply the
ideal type of the form which is to give the soul, when reincarnated,
the best means of expression; others take charge of these models and
entrust them to entities whose sole mission is to keep them before
their mental eyes and guide the thousands of "builders" who build
round them the atoms which are to form the tabernacle of flesh in its
minutest details; these Liliputian builders may be seen at work by the
inner eye; they are as real as the workmen who construct material
edifices in accordance with an architect's plans.

That everything may be faithfully reproduced in form the entity that
