The Neville Goddard revision technique involves mentally rewriting a past event to change its emotional and factual reality. To perform this, you first mentally revisit an unwanted memory, then in a relaxed, drowsy state akin to sleep (SATS), imagine the event happening differently and more favorably. Relive this revised version repeatedly in your imagination until it feels real, and the original memory fades, thereby shifting your inner state and future reality. 

Step-by-step guide to the revision technique

1. Identify the memory:

   Choose a past event that did not go the way you wanted, or choose to revise the events of the day before you go to sleep. 

2. Mentally revisit the memory:

   Bring the original event to mind, focusing on the details and feelings without judgment. 

3. Rewrite the scene:

   Imagine the event playing out differently, with a favorable outcome. For example, if someone yelled at you, imagine them suddenly apologizing and speaking kindly. 

4. Enter a relaxed state:

   Get into a comfortable position, relax your body, and enter a state akin to sleep (SATS). This can be done at any time, but before bed is recommended. 

5. Relive the revised scene:

   Play the new, revised version of the event in your imagination over and over again. Use all your senses to make it feel as real as possible. 

6. Feel the new reality:

   Repeat the revised scene until it begins to have "the tones of reality"—that is, until it feels as though it actually happened that way. 

7. Let go:

   Once you feel you have succeeded, let the thought go. You do not need to keep repeating it compulsively. Allow yourself to move on with your day, knowing that you have effectively changed the past in your imagination.
