l energy. The sum of
material causes potentially contains the energy manifested in the
sum of effects. When the effectuating condition is added to the
sum of material conditions in a given collocation, all that happens
is that a stimulus is imparted which removes the arrest, disturbs
the relatively stable equilibrium, and brings on a liberation of
energy together with a fresh collocation(_gu@nasannives'avis'e@sa_).
As the owner of an adjacent field in transferring water from one
field to another of the same or lower level has only to remove
the obstructing mud barriers, whereupon the water flows of itself
to the other field, so when the efficient or instrumental causes
(such as the sculptor's art) remove the barrier inherent in any
collocation against its transformation into any other collocation,
the energy from that collocation flows out in a corresponding
manner and determines the collocation. Thus for example the
energy which collocated the milk-atoms to form milk was in a
state of arrest in the milk state. If by heat or other causes this
barrier is removed, the energy naturally changes direction in a
corresponding manner and collocates the atoms accordingly for
the formation of curd. So also as soon as the barriers are removed
from the prak@rti, guided by the constant will of Is'vara, the reals
in equilibrium in the state of prak@rti leave their state of arrest
and evolve themselves into mahat, etc.

Change as the formation of new collocations.

It is easy to see from what we have already said that any
collocation of atoms forming a thing could not change its form,
unless the barrier inherent or caused by the formation of the
present collocation could be removed by some other extraneous
instrumental cause. All gross things are formed by the collocation
of the five atoms of k@siti, ap, tejas, marut, and vyoman. The
difference between one thing and another is simply this, that its
collocation of atoms or the arrangement or grouping of atoms
is different from that in another. The formation of a collocation
has an inherent barrier against any change, which keeps that
collocation in a state of equilibrium, and it is easy to see that
these barriers exist in infinite directions in which all the other
infinite objects of the world exist. From whichever side the barrier
is removed, the energy flows in that direction and helps the

formation of a corresponding object. Provided the suitable barriers
could be rem
