Frustration
The animal soul is not a cruel human who has lost her heart.
As we come to understand this manifestation, we begin to see that
its exaggerated destructiveness and hateful quality are actually
reactions to frustration. Because the instinctual self is not
allowed to be powerful and effective in getting its way, its power
turns into destructive hatred and heartless reactivity. The particulars
of the structure connect with one's early history in relation
to power, control, destructiveness as well as the need to protect
the vulnerable and loving heart. When we are finally able to experience
this animal form without either rejection or judgment or acting
out, it transforms into its original form. This turns out to be
an animal kind of power and energy, calm and confident, peaceful
but ready to act with full power and energy. The opening of this
experience removes the negativity associated with frustration.
