"All shallow roots (egoic projections) have to be uprooted, because they are not deep enough to sustain you. The illusion that shallow roots can be deepened and thus made to hold is one of the corollaries on which the reversal of the Golden Rule, referred to twice before, is balanced. As these false underpinnings are uprooted (or given up), equilibrium is experienced as unstable. But the fact is that nothing is less stable than an orientation which is upside down. Anything that holds it that way is hardly conducive to greater stability.

... “Hurling something you do not want... to someone else,” which is what projection does, “is the opposite of the Golden Rule” because it means giving to others what you do not want given to you. ~ACIM T-1.V.6 - Complete Edition
