Everything exists right now…everything!
I have read so many books on manifestation and they all say that the most important thing is to imagine/believe that your desire has already manifested here in the present and live as though it has. For example, Neville Goddard says that your imagination creates reality so you merely need to “believe” that you have what you desire now, in the present, and it will appear.
You have to decide for yourself in your own personal human experience what you prefer to believe is real for you and what isn’t. The simple way to maintain a belief about a manifested desire is to choose and decide to change your belief of what you think is in existence and what isn’t. You are at both sides of the chess board in this world. You make all the moves and then also make the counter moves.
Just because we can’t see something with our eyes doesn’t mean it is non-existent. There are plenty of things in this world that we can’t see, hear, or touch, yet we believe in them completely. You have to want to stay positive and in the right vibration. You have to want to make feeling good the most important thing in your life. Even more important that getting your desire, you have to be the change that you want to see manifest in your life.
If you can get to the point and believe that you already have everything you desire, then you can start heading down the path of seeing different things pop up here and there. Just choose the belief that feels best to you in every moment. It is possible to have chaos going on around you and still hold the vibration of your choosing.
