Excerpts from the book ‘Ask and It’s Given’ By Esther and Jerry Hicks.

Why does saying No to it  

Means saying Yes to it?  

Your vibrational Universe has the law of attraction as its basis. That means that your universe is about inclusion. When you give your attention to something that you desire and you say yes to it, you are including it in your vibration but when you look at something you do not want and you say no to it, you are including it in your vibration. When you give more attention to it, you do not include it, but you cannot exclude anything that you are giving your attention to, because your intention to it includes it in your vibration, every time, without exception.
