I've just been reading 'Every Word has Power' by Yvonne Oswald. It was another of those books which I thought I'd better buy, after standing for ten minutes reading it in the shop and deciding that I really didn't want to leave it behind
It gives techniques, tips and exercises to help people change how they speak in small ways, gradually eliminating all the negative words and sentences by turning them around into postive ones - yes there is a way to speak negatively in a postive manner!!
It works alongside and complements the LOA, also is written in a very straight-forward, no-nonsense sort of way but has its spiritual angle as well, with some lovely affirmations to use particularly before sleeping. There are chapters on decision making, focusing, communicating, awareness, letting go, relationships and spiritual connection.
I raced through it to begin with, but am back reading it properly now. I'd certainly recommend it to anyone who tends to slip back into negative thought and speech patterns despite their best intentions!
