The Universe recognizes feelings. The reason visualization works is because it creates feelings in you that radiate outwards. It is sending the signal to the universe that this is what you want to experience.
Like Attracts Like
The Law of Attraction states what is like unto itself is drawn. If you feel good you will attract more things to feel good about, if you feel bad you will attract more things to feel bad about. The universe will make sure you keep feeling what feeling. It is your responsibility to become aware of what you focus your time on to give your attention to. If you want to live an amazing life don’t spend any time thinking about what you don’t want. For example, if you can’t pay that bill right now don’t think you can’t, think about how the money is on its way to you so you can pay that bill.
How to focus more on your feelings?
If you want your manifestations to work after asking the universe for what you want, feel how it would feel if you already had it. This way you won’t create the feeling of the lack of it.
Visualize
When you are visualizing, see the scene from the first perspective, through your own eyes, be in the scene not watching the scene, not watching the scene from the outside. Live the life in the scene so you leave the scene with full embodiment. If you want your house to have a pool, actually swim in the pool. Feel the water on your skin, feel the water on your skin, feel the splashes you make in the water. Try to sense everything you can in your visualizations.
Meditate
If you are someone who struggles with controlling your thoughts, start a meditation practice to get better control of your mind so you can master being only an observer of your thoughts.
Scripting
Scripting can work miracles in your life. Scripting helps you go beyond just thinking about what you want and puts you in the place of already having it. For example instead of “I want to buy new clothes” write “I am so grateful and thankful I was able to buy to purchase these new clothes”. Write about the day you had while shopping and how it made you feel, get as specific as possible.
