I read Louise Hay's book quite awhile back. When I read the book, she was still alive. I was very inspired by her idea that all disease comes from stress. If you caught a cold, it's not because you got exposed to germs or a virus - we get exposed to germs and viruses everyday - the real reason is because we were stressed and our immune system wasn't strong enough to defend our bodies against those intruding disease.
She provides a list of ailments and what their probable cause is and what our new thought pattern should be. For example, the probable cause of anxiety is not trusting the flow and the process of life. The new thought pattern should be "I love and approve of myself and I trust the process of life. I am safe." The probable cause of blackheads is small bursts of anger and the new thought pattern should be "I calm my thoughts and I am serene." Or if you have breathing problems, it is probably due to fear or refusal to take in life or not feeling the right to take up space or even exist. The new thought pattern should be "It is my birthright to live fully and freely. I am worth loving. I now choose to live life fully,"
She is the queen of affirmations and recommends everyone to write, say, sing affirmations everyday. From the moment you wake up, repeat affirmations over and over.
I am wonderful and I love you. This is one of the best days of my life. Everything is working out for mi highest good. Whatever I need to know is revealed to me. Whatever I need comes to me. All my relationships are harmonious. I am deeply fulfilled by all that I do.
She also advocates feeding the body with good nutrition as part of self love, which probably inspired me to study nutrition. Go on a diet of negative thoughts, and your weight will take care of itself.
