I am not able to meditate.

For years my only dream is to meditate, but i cant do that.

And today i got a thought why i could not do this,
that is
my inner mind is not clean nor clear
i hate lots of people in these days
i see people as a friend or enemy
These awful minds prevent me from meditating.
I cant deceive myself.

Meditation needs good and clean spirit and mind,I think.
