From a Treatise on White magic. by Alice. A Bailey.

The self must know where the mind is concentrated at all times in different aspects
of the divine whole. The divine mind in Nature.Train the mind to reach the Universal
Mind. All life is vibration, and the result of vibration is form.
1) The mechanistic school of psychology, lays the emphasis on structure, and takes
the reaction of the mental aspect, regarding the structure, as being responsible for
all the lines of conduct and characteristics, which man displays as both normal and abnormal.
2) The introspective school, has the conscious something responsible for conditions
said to be " aware of awareness ." This school recognizes certain aspects of conduct
or reactions, or problems as unable to solve, under the mechanistic process.
They go nearer to the occult.
3) Then the vitalists, or that group who admitting the fact of the structure, yet regard
it as subjected to the influences of energies, and forces emanating from an outer
environment. Those are the energies of a wider nature, than those entirely from the self.
They number among them, the great basic urges for which Nature itself is responsible,
and which can be seen and felt in units of organic life, other than human. The truth
which is safe guarded in all these schools is One Truth.
There is a mechanism through which the real man functions, and there is a structure
he has built in conformity to the laws of Nature, These he has learnt to use.
In accordance with the subjective school, he must learn to differentiate between
himself as a conscious center of awareness.
The I of intelligence, and the apparatus through which he contacts the outer world.
When the eye of the user of the mechanistic can do this, he becomes aware of another
fact, and that is that not only is he a generator and user of energy, but there are forces
and energies in Nature and the planet which he can also respond to and learn
to adapt and use.
The three present schools, who are the custodians of the facts under the present
system, are occupied with disproving each others theories. They are all correct
in their facts, and they all need each other, and from a blending of the three presentations
a forth will emerge, which will be nearer the truth than any of the separated three.
Psychology is reluctant to let individual fate into its field. It does admit that we each
have our own make up, and that we are definitely, even defiantly a unique individual.
When it comes to accounting for the spark of uniqueness, and the call that keeps
us to it, psychology too is stumped.
Its analylitical methods, break down the puzzle of the individual, into factors, and traits
of personality into types, complexes, and temperaments, attempting to track the secret
of individuality, to substrata of brain matter and selfish genes.
The more strict school, kicks the question right out of the lab, packing it off to
parapsychology, for the study of paranormal " calling " or to research stations
in the distant colonies of magic, religion, and madness.
At its most bold, and most barren psychology accounts for the uniqueness of each
by a hypothesis of random statistical chance.
