Sure stating affirmations in English are very effective when infused with energy.
That is why we use them, the difference is that even when just saying words of power without knowing how to vibrate them properly it still has an effect on you.
There is a huge difference in the power of our spoken languages and the ancient languages where the words of power come from.
Just as a simple example.
The rune Thurisaz means Thorn in english.
When simply reading Thurisaz it activates it's power, however when simply reading Thorn it does nothing.
When Vibrating Thurisaz it creates a very powerful reaction, when infusing it with energy much more so.
Try to do the same with Thorn. It does nothing.
That is because English is not a magical language.
When stating affirmations you can use positive ones and negative ones, but stating an affirmation in English backwards doesn;t have any effect. It simply doesn't work like that, take it for what you will..
So stick with positive and negative affirmations and you'll be fine.
Now if we knew enough words in Sumerian, or even Enochian to affirm affirmations you can be certain the affirmations spoken in those languages are going to have a lot more power even on their own.
Just because millions of people speak English that doesn't make it magical or powerful.
When people speak English they don't infuse it with power, they simply give meaning to the words, that is a very different thing.
In order to give power to an affirmation you must raise your energy and then program this energy by stating with a strong focused mind what you want it to do. This creates a visualization in your mind because the words spoken have meaning to you and thus create a thought, a will. This will is programmed into the energy by your mind. Then you must direct this energy to do what you have programmed in to it.
Now when speaking in a magical language the words themselves are filled with power and they activate their power without you needing to program anything, all you need to do is simply direct the power already present in the words to the purpose you want it to serve you.
Simply saying the Runes a few times will activate their power even when not vibrating them.
That is evidence of their power.
When you speak English the only way you are able to infuse your words with power is when you actually activate and raise your own energy and then project your energy through your voice.
Also about the RTR's. Even if you don't raise your energy prior it still creates much more power simply saying these words than if you were to read the translated verse in English backwards.
Such is the nature of it.
