Neville insisted that imagination works through feeling, not effort. The aim is not to picture a scene at arm’s length but to feel, now, the relief and naturalness of the wish already fulfilled.
A vivid image you don’t believe does little. A simple feeling you accept as true does much. The test is always inward: does it feel real?
Summon the feeling of one wish fulfilled; hold it until it feels ordinary.
Describe the felt tone of your wish as already accomplished.
