I shall soon read the book "mindfullness in plain english"
and I guess my question will be explained there...
But until I've read this book could anyone please tell
me at what do I have to point my awareness during meditation
according to vipassana? (and perhaps according to zen as well

)
For your information...
I have learned what I guess must be some kind of unstructured meditation in the book "I am that" (by nisargadatta)
and i have practiced it quite a lot the past 2 years. Even though I like the results i am wondering
what the object of concentration in vipassana (or zen) actually is??!!!
Until now, when doing meditation i have always been attentive of my whole body as a whole,
all the thoughts as a whole and in fact all sounds and sensations outside of me as a whole.
I mean, i sort of give all my attention to
everything which I can be aware off, all at once,
without differentiating whether something is
supposedly painful or pleasurous, interesting or boring,
internal or external.
In this kind of meditation, there are not really any thoughts (although they obviously
popup sometimes and try to distract me) - and i feel very relaxed, yet very energetic (as in: not feeling lazy one bit).
In this kind of meditation, the chattering mind, the "ego experience" is absent...
yet i feel very much present. I feel present not as a person with likes or dislikes,
not as the body, but as Awareness itself that shines it's attention onto "everything at once" (as explained earlier).

In meditation I feel like i am the dot (awareness) and i give attention to everything inside and outside me
in all directions (the giving of attention is represented by the arrows)
but in every direction where attention is aimed at,
there is unveiled more awareness... (and it feels like this attentiveness or awareness is me)
which i again use to give attention in all directions...
so basically meditation for me is sort of like the picture below.
I like it, but at times it has definately been kind confusing because there is no
"fixed" point of concentration such as the breath...
but instead my way of concentrating is to forever give attention in all directions. (sort off)

In vipassana/zen, if the point of concentration, or the way of concentrating,
is different and more effective than the -at times kind of confusing way- I have been practicing until now...
then I hope I shall soon realize the inferiority of my method and switch to a superior one!
I guess it's really about time I should start to read the "mindfulness in plain english" book
I give thanks to those who answered my question!! and those who have not, thanks for nothing
