The other probable actions, however, are as valid as they ever were, though you have not chosen to actualize them physically. They are carried out as effectively as the one you chose to accept. If there was a strong emotional charge behind one of the rejected probable actions, it may even have greater validity as an act than the one you chose.

Go back to our man at the telephone, mentioned earlier. Let us say that he tells his friend he will not go. At the same time, if he imagines that he took another alternative and agreed on the engagement, then he might experience a sudden rift of dimensions. If he is lucky and the circumstances are good, he might suddenly feel the full validity of his acceptance as strongly as if he had chosen it physically. Before he realizes what is happening, he might actually feel himself leave his home and embark upon those probable actions that physically he has chosen not to perform.

Such an experiment will not carry you too far, however, and the probable self who has chosen the action that you denied, is in important respects quite different from the self that you know. Each mental act opens up a new dimension of actuality. In a manner of speaking, your slightest thought gives birth to worlds.
