Most recently, I've experienced this phenomena as I turned to a page in a book called Alchemy of the Heart: How to Give and Receive More Love by Elizabeth Clare Prophet and Patricia R. Spadaro. I don't know much about these authors but the book jacket says that Prophet "has pioneered techniques in practical spirituality, including the creative power of sound for personal growth and world transformation." The information about Spadaro says that she has a "special interest in practical spirituality, gnosticism, and the mystical paths of the world's religions."
The section I turned to is called "Heart Perspectives" and talks about clearing the heart with prayers, affirmations, and visualization."
The authors write that you can use the affirmations that they suggest to "invoke the alchemy of violet flame to clear the painful memories of past experiences."
They can also help clear the subconscious, which accepts the [negative judgements of others]... The violet flame can resolve these patterns of consciousness and free us to be more of our real self.
Many affirmations use the name of God "I AM" to access spiritual power. "I AM" is short for "I AM THAT I AM," the name of God revealed to Moses when he saw the burning bush. "I AM THAT I AM" means simply but profoundly As above, so below. As God is in heaven, so God is on earth within me. Right where I stand, the power of God is. Thus, every time you say, "I AM ..." you are really affirming "God in me is ..."
Visualize violet-colored flames within your heart softening and then melting away any hardness of heart-transforming anger into compassion, bitterness into sweetness, anxiety into peace. You can recite any affirmation once, three times or as many times as you want ..."
I've already added this one to my list of affirmations, meditations, and prayers.
