Personally, I like sitting confortably, in a Buddha-like position, not quite like the Buddha images you see:
But similar, as in hand position, but not feet. I am not that flexible yet (=. And the important thing for me is to be confortable.
Next, I go to a dream-like state, were I try to get rid of every thought. Words come to my head, but I vanish them... Images come to my head, but I vanish them... Only a few minutes of an hour meditation are worth it, the rest is the mind trying to fight that state, going to the past or future.
I have realized the few moments I get of total darkness, are the moments with more light in them. Is not everytime I manage to reach this state, it is difficult for me, with the brain in the way.
I found that the best method for me is to concentrate on the deepest breathing humming the OMM to my inside while I breath.
But just yesterday I thought, that just thinking about OMMM is still thinking...
You have to be in total blank, no thoughts, no images, no sounds... It´s all in your brain... So, I have come to the conclusion that through many days of meditation, I´ve only being meditating a few minutes per hour...
I am curious, to hear from meditators their methods and conclusions so far...
