The psychic nature is built up through the image-making power, the
power which lies behind and dwells in mind-pictures. These pictures
do not remain quiescent in the mind; they are kinetic, restless,
stimulating to new acts. Thus the mind-image of an indulgence
suggests and invites to a new indulgence; the picture of past joy is
framed in regrets or hopes. And there is the ceaseless play of the
desire to know, to penetrate to the essence of things, to classify. This,
too, busies itself ceaselessly with the mind-images. So that we may
classify the activities of the psychic nature thus:

6. These activities are: Sound intellection, unsound intellection,
predication, sleep, memory.

We have here a list of mental and emotional powers; of powers that
picture and observe, and of powers that picture and feel. But the
power to know and feel is spiritual and immortal. What is needed is,
not to destroy it, but to raise it from the psychical to the spiritual
realm.

7. The elements of sound intellection are: direct observation, inductive
reason, and trustworthy testimony.

Each of these is a spiritual power, thinly veiled. Direct observation is
the outermost form of the Soul's pure vision. Inductive reason rests on
the great principles of continuity and correspondence; and these, on
the supreme truth that all life is of the One. Trustworthy testimony,
the sharing of one soul in the wisdom of another, rests on the ultimate
oneness of all souls.

8. Unsound intellection is false understanding, not resting on a
perception of the true nature of things.

When the object is not truly perceived, when the observation is
inaccurate and faulty, thought or reasoning based on that mistaken
perception is of necessity false and unsound.

9. Predication is carried on through words or thoughts not resting on
an object perceived.

The purpose of this Sutra is, to distinguish between the mental process
of predication, and observation, induction or testimony. Predication
is the attribution of a quality or action to a subject, by adding to it a
predicate. In the sentence, "the man is wise," "the man" is the subject;
"is wise" is the predicate. This may be simply an interplay of thoughts,
without the presence of the object thought of; or the things thought
of may be imaginary or unreal; while observation, induction and
testimony always go back to an object.

10. Sleep is the
