Attack, like defense, is a means by which the separated attempt to maintain their hold on the little in the world they claim as their own. It never succeeds because its premise is always the reality of separation, which damages both the one who who wields it and the one against whom it is wielded. Whenever we see a brother or sister as a body, or as having something we do not, then we are effectively attacking them. A Course in Miracles asks us to be vigilant to these forms of attack. Noticing them is the first step in undoing them.
