Hi Rooney,
I think it is normal for us to feel that way. I do have 'bad'
and 'good' days when meditating. During the 'bad' day, my mind will
flicker and start to wonder.
I THINK... the reason why you feel restlessness could be due to
the fact that you think you are restless before the meditation.
Don't be so particular about it. Just sit down, relax, breathe!
Meditation is about watch your mind, watching your
breath.
The common things you will think about is:
1) Events which had past (either happy, or sad e.g. boss
scolding you)
2) Events which has not come
If you are sitting for 5 mins, just tell yourself, nothing in
this world can disturb you. This is your 5 mins. Unhappy or happy
events which has passed, has passed, you cannot do anything about
it. Happy or unhappy events which has not arrive, you also cannot
do anything about it. Leave the worrying till next time.
Then notice what are you feeling? what are you thinking? where
does your restlessness come from? where does it goes? what happens
next?
Try to lock your attention to the breath. feel the sensation of
the air at the tip of the nose or whatever object you are
meditating on. When you realized you ha drifted, come back to the
breathing gently. It is not your fault, this is how the mind
reacts.
Most importantly, enjoy the blissfulness which stays when you
are calm and peaceful, if possible, feel the joy =)
It is sad when most people do not know how to appreciate this
but you can! continue to practice hard. This wholesome feeling will
be the motivation to bring you back to practice in the future.
Hope it does help.
