Reactivity
It is in the nature of mind to be in a constant state of reactivity;
and here we do not simply mean what is implied in the usual sense
of the word. We mean something more fundamental: that the individual
is always reacting with certain very limited patterns of emotion
and behavior which reflect the self-image he is identifying with,
and that this self-image is itself a reaction, in two senses:
first, that the specific self-image that is operating is automatically
elicited by the situation, and second, that the self-image is
itself a construction made up of reactions to past events from
early childhood. This self-image is thus never a spontaneous response
or a free choice, but is always a compulsive reaction. (The Pearl
Beyond Price, pg 56)

Reactivity has been understood by many of the wisdom traditions
as antithetical to our true nature, and many inner techniques
for transformation are one way or another to disengage from reactivity.
We see here that the problem with reactivity is that it annihilates
presence. It means the soul leaves her ground, and it further
implies the absence of inner trust necessary for abiding in one's
true nature. It reflects the position that if one continues to
be present one will suffer more. Therefore, besides trying to
control the environment, the soul learns to control her inner
experience. More precisely, the soul experiences the inadequacy
of holding as an inner disruption, an undesirable and threatening
difficulty. She reacts to these with an array of inner postures
and strategies that end up dissociating her even more from her
nature. (Inner Journey Home, pg 160)
