After reading some things on meditation from buddhanet, I feel I have gained a foothold with medtation, allbeit maybe a small one. I still only seem to be able to meditate for around 10-15 minutes, but those minutes spent meditating feel rather different to how they have felt for 3 years prior.
I have been using a model where you focus on the abdomen as it rises and falls, when your thoughts go astray you should make whatever that may be the centre of your thinking until it passes. So for example I hear something outside, I focus on that and then return to the abdomen.
I have realized that the mind is constantly being hit with heaps of stimuli, I knew this before but I now I realize it on a different level. It is like being in a tin hut in a heavy hail storm. Also I have seen a few ways in which my mind works, I have seen how it has 'learnt' to cope with hyperchondriasis. When I get a prang about being sick or ill, it conveniently replaces that thought with something else really quickly and pushed it to the back of my mind. It has created a sort of blankspot if you will.
However I have been stopped in my tracks most of the time whilst meditating because for some reason my breathing becomes shallow or I feel sick in the pit of my stomach, somtimes both. I don't know why that is, any thoughts?
