I wanted to let you know that your request wasn't blown-off or anything. I think the issue is that there aren't very many people who are fairly active on this board (from what I've seen lately).
I don't know that I am qualified to help you, as I haven't significantly achieved this yet. Some twitching, but that's it. And lately, I haven't been able to muster much of that from over-practice. I can make it twitch for pulling, but can't seem to push anything at all.
I don't think that its that no one wants to help I know a lot of the people who use this forum are professionals (as in work) so they drop in whenever they can but we all understand we are busy.
Push pull.
Push pull Technique is achieved by starting small a bent piece of paper. Remember the blocks are all in your head. I know this is achievable as I have done it. Focus your attention on edges whilst finding your altered mindset. Visualize it happening as you would psiwheel let your attention self become the air around it and connect. If I were to describe the feeling of connection it is unconditional love (not the valentines day version) Once you connect to the area in this way you become the area. The higher mind is then free to activate your intention. Relaxed peripheral awareness. Start with paper then foam then cardboard. I have worked my way up to toy monsters. KEep with it START SMALL PAPER. (Record your results) Training is the only way to get better and push larger objects.
