We are energy and because we are energy our wishes can be manifested with ease. Energy is like a magnet that attracts what is inside ourselves to the same energy externally.
That is how things get created.
From though to feeling to action to result. May be we can say: You have a strong feeling inside of yourself, then you put words to that feeling and before you go into action you see the picture of how it looks. Now you are so excited therefore you go into action and BINGO the result is exactly the picture you saw.
How did it happen you may ask yourself?: The energy inside of yourself with the help of the angels that assist you, created the coming together of the two energies, called external energy to your internal desire therefore your WISH came true.
