Your right come to think of it. A lot of things I wanted for a long time manifested when I was in a neutral peaceful feeling state:)

The best advice I can give you is to get into the Vortex anyway you can, preferably in the morning and stay there. Then you won't miss what you don't have and you will feel good Now :)

Anytime you feel a dip in your vibration and your noticing the lack do something that helps you feel good :)

When you take your focus of manifesting  and make getting into the Vortex and staying there a daily habit, manifesting will become very easy for you:)

To answer your question directly here a few techniques to bring you to Neutral on a subject.

Meditation

EFT

Quantum Entrainment or QE

Chinese Energetics

Sedona Method

THT or Two Hands Touching

Abraham-Hicks process you might find useful: PIVOTING

Two simple techniques that always works for me are from Frank Kinslow's "Quantum Entrainment" which Satori has already mentioned. The other one is a technique from Eckhart Tolle's book "The Power Of Now" which has similarities to what Fairy Princess mentioned.

These are so simple and easy to use and that's why I get so much out of them.

The QE Technique - Ask yourself out loud or in your head the following question or questions when you want to release unwanted thought.

• "Where will my next thought come from?"
• "What color will my next thought be?"
• "What will my next thought smell like?"

Try any one of those right now and pay attention to the gap or blankness between your thoughts. Continue to use these simple questions as much as you need to stay in your quiet place. You can also try to become the observer of your thoughts and watch them pass by as if you were watching them on a movie screen. Then, if one pops up that you can't let pass by as an observer, ask one of the questions above and pay attention to the stoppage of thoughts. I highly recommend any of the Frank Kinslow books.

Eckhart Tolle Technique - Simply put your attention into your body. Focus on your body in any way that feels best. You could focus on your foot for fifteen seconds. Then you could work your way up to your calf for 15 seconds, your thigh, your torso, etc. You could also just focus on your entire body at once. There is no wrong way to do this.

Feel the warmth, the blood flow, your heart beat, the texture of your skin. Pretty much anything that puts your focus and attention on your inner self. If your body starts to tingle when you are focusing, become aware of that euphoric feeling and hold your attention on that for as long as you can. Milk it for all it's worth. I also recommend anything from Eckhart Tolle.

I have been using these two simple techniques consistently for some time now and they always put me in the zero point of no thought when I need it. Quick, easy, and simple, just the way I like it!

Our @Satori's got your answer, @lozenge123. Any way you approach this, you will need to have both feet firmly planted in the Vortex. That happy state allows all the good that is flowing to you to actually reach you. I would just like to add a little practice I have used that has helped me to keep my mind out of The Box. Its not a big deal, but it helps.

You can't really stop thinking, so you have to replace what you are thinking.

I have had some success with this by deciding ahead of time to keep a neutral subject or two in my pocket, ready to pull out and ponder when I need to replace a thought I don't want to entertain. Thing is, you do have to decide ahead on a few subjects you can use, because when your mind slips into that well-worn groove of that special thing you don't want to think about, it's so hard to think creatively in that moment. Or, it is for me. :) That groove is deep from repeated trips down fantasy lane, and easy to slip into. The good news is, it will get much less so as you manage to ignore it.

The handy replacement thought can be anything you find facinating, something you don't have a whole lot of information on, something you have questions about. We have the greatest collection of questions in the world, IMO, right here at IQ.

For instance, right now for me, I'm keeping the subject of chakras on hand, also mental telepathy, and dream meanings. Things I know something about, but have a million questions to ask, and have nothing really to do with the stuff in The Box. Let your curiosity carry you away, enjoy finding the answers, have fun! That will serve the dual purpose of getting you out of your way, and keeping you in a happy place. :)

Two Hands Touching is a fast easy way to 'let go' or reach a neutral point. Press the palms of your hands together and close your eyes. Ask yourself quitetly in your head, "What do my hands feel like?" Don't try to namy the feelings, just feel the answer in your hands. Don't try to think or not think, just feel your hands. Do this for at least 30 seconds, and as long as you want. Peace
