You are correct that Neville Goddard is a christian metaphysician. I have copied and pasted some text below from one of his lectures that explains his thinking and main teaching:
From BRAZEN IMPUDENCE:
A new idea will not become part of your common currency of thought until it has been repeated over and over and you begin to live by it.
You have been taught to believe that God exists outside of you, but I say you are all Imagination. That God exists in us and we in him. That our eternal body is the Imagination, and that is God Himself. I mean every word I have just said, but it is a new thought. Until this new idea becomes a part of your thinking, every time you hear the word, “God,” your mind will go out to something you have conceived God to be.
I will now share with you a very personal story. I tell it to illustrate a principle. Society blamed this lady for what she did, and she paid the price, but I was the cause of her misfortune. I am not going to justify my story and if you can’t take it, I’m sorry. When I first told it, one lady was very upset and I regret that; but I have noticed that when someone has recently given up alcohol, tobacco, meat, or sex, they invariably condemn the state. They feel too close to it to feel secure. I am not saying that this lady had a similar experience where she was the victim; I am only speaking of a principle. Now here is my story:
When I decided to marry the lady who now bears my name I applied this principle. At the time I was terribly involved. I had married at the age of eighteen and became a father at nineteen. We separated that year, but I never sought a divorce; therefore, my separation was not legal in the state of New York. Sixteen years later, when I fell in love and wanted to marry my present wife, I decided to sleep as though we were married. While sleeping, physically in my hotel room, I slept imaginatively in an apartment, she in one bed and I in the other. My dancing partner did not want me to marry, so she told my wife that I would be seeking a divorce and to make herself scarce - which she did, taking up residence in another state. But I persisted! Night after night I slept in the assumption that I was happily married to the girl I love.
Within a week I received a call requesting me to be in court the next Tuesday morning at 10:00 A.M.. Giving me no reason why I should be there, I dismissed the request, thinking it was a hoax played on me by a friend. So the next Tuesday morning at 9:30 A.M. I was unshaved and only casually dressed, when the phone rang and a lady said: "It would be to your advantage, as a public figure, to be in court this morning, as your wife is on trial." What a shock! I quickly thanked the lady, caught a taxi, and arrived just as court began. My wife had been caught lifting a few items from a store in New York City, which she had not paid for. Asking to speak on her behalf I said: "She is my wife and the mother of my son. Although we have been separated for sixteen years, as far as I know she has never done this before and I do not think she will ever do it again. We have a marvelous son. Please do nothing to her to reflect in any way upon our son, who lives with me. If I may say something, she is eight years my senior and may be passing through a certain emotional state which prompted her to do what she did. If you must sentence her, then please suspend it." The judge then said to me, "In all of my years on the bench I have never heard an appeal like this. Your wife tells me you want a divorce, and here you could have tangible evidence for it, yet you plead for her release." He then sentenced her for six months and suspended the sentence. My wife waited for me at the back of the room and said: "Neville, that was a decent thing to do. Give me the subpoena and I will sign it." We took a taxi together and I did that which was not legal: I served my own subpoena and she signed it.
Now, who was the cause of her misfortune? She lived in another state, but came to New York City to do an act for which she was to be caught and tried. So I say: every being in the world will serve your purpose, so in the end you will say: "Father forgive them, for they know not what they do." They will move under compulsion to do your will, just as my wife did.
I tell this story only to illustrate a principle. You do not need to ask anyone to aid you in the answer to a prayer, for the simple reason that God is omnipotent and omniscient. He is in you as your own wonderful IAmness. Everyone on the outside is your servant, your slave, ready and able to do your will. All you need do is know what you want. Construct a scene which would imply the fulfillment of your desire. Enter the scene and remain there. If your imaginal counselor (your feeling of fulfillment) agrees with that which is used to illustrate your fulfilled desire, your fantasy will become a fact. If it does not, start all over again by creating a new scene and enter it. It costs you nothing to imagine consciously!
In my own case the scene was a bedroom of an apartment, with my wife in one bed and I in the other, denoting that I was no longer living in a hotel alone. I fell asleep in that state, and within one week I had the necessary papers to start action on a divorce.
This is what the Bible teaches. It is my text book. "Whatever you desire, believe you have already received it and you will!"
There is no limit to the power of belief or to the possibilities of prayer, but you must be brazenly impudent and not take No for an answer. Try it! When I say you are all imagination, I mean it. While standing here on the platform I can, in a split-second, imagine I am standing on the outside, looking at this building. Or, in another second be in London and view the world from there. You say that’s all hallucination? That it is all in my imagination?
Neville's followers have obtained great success after following his techniques. They have manifested jobs, partners, money, fame etc. I want to try it, but I'm afraid of karmic implications, if any. I asked this question but my question was removed from the Neville forum.
I hope you now understand what I am trying to ask you.
1. Is prarabdha karma changeable?
2. If yes, then why did Ramana Maharshi say that it is not?
3. Does "meddling" with your karma create more karma or result in implications?
Thank you!
