"The nature of sin is not immorality and wrongdoing, but the nature of self-realization which leads us to say, 'I am my own god.' This nature may exhibit itself in proper morality or in improper immorality, but it always has a common basis - my claim to my right to myself." ~ Oswald Chambers in My Utmost for His Highest (Entry for October 5 - written between 1911 & 1915!)Self-realization is not a new thing, nor necessarily a bad thing. But Chambers took note of it's dangers nearly 100 years ago. Without God, the self becomes the arbiter of good and evil. This was the sin of the garden. And the same devil tempts us today with the same proposition: "You shall be like God." This is a fundamental flaw in the teaching of the Secret and those who advocate it's doctrines.
And note that we are not talking about whether the teachers of the Secret are moral or immoral. I am sure that many who profess to follow universal principles like the Law of Attraction are quite nice and giving people. That is not the issue. The issue is idolatry. Ultimately, the Secret is about claiming my right to myself.
If ever we travel within to find ourselves, rest assured, it will be a very short trip.
