All three aspects of the spirit are active all the time
during evolution but the principal activity of each aspect will

When the threefold spirit had evolved the threefold body
and gained control of it through the focus of Mind, it
commenced to evolve the threefold soul by working from
within. How much or how little soul a man has depends
upon the amount of work the spirit has done in the bodies.
This has been explained in the chapter describing
postmortem experiences.
As much of the desire body as has been worked upon by
the Ego is transmuted into the emotional soul, and is
ultimately assimilated by the human spirit, the special
vehicle of which is the desire body.
As much of the vital body as has been worked upon by
the life spirit, becomes the Intellectual soul, and it builds the
life spirit, because that aspect of the threefold spirit has its
counterpart in the vital body.
As much of the dense body as has been worked upon by
the Divine Spirit is called the Conscious soul, and is
ultimately merged in the Divine Spirit, because the dense
body is its material emanation.
The Conscious soul grows by action, external impacts,
and experience.
The Emotional soul grows by the feelings and emotions
generated by actions and experiences.
The Intellectual soul, as mediator between the other two,
grows by the exercise of memory, by which it links together
past and present experiences and the feelings engendered
