Quote from A Course in Miracles Text Chapter 30 - THE NEW BEGINNING.

T-30.IV.3. The gap that is not there is filled with toys in countless forms. 2 And each one seems to break the rules you set for it. 3 It never was the thing you thought. 4 It must appear to break your rules for safety, since the rules were wrong. 5 But you are not endangered. 6 You can laugh at popping heads and squeaking toys, as does the child who learns they are no threat to him. 7 Yet while he likes to play with them, he still perceives them as obeying rules he made for his enjoyment. 8 So there still are rules that they can seem to break and frighten him. 9 Yet is he at the mercy of his toys? 10 And can they represent a threat to him?
