Meditation is a state of thoughtless awareness: Meditation is
a state of non-emotional, non-sentimental, non-thinking
awareness. When you are simply aware, when you become a
pillar of awareness. When you are simply awakened, alert,
attentive. When you are just a pure awareness.

How to enter into it? The Zen people have a special word for
the entry, they call it
hua t'ou. This Chinese word means ante-
thought, or ante-word.
The mind, before it is stirred by a
thought, is called
hua t'ou.
Between two thoughts there is a
gap, that gap is called
hua t'ou.


Watch. One thought passes on the screen of your mind – on
the radar screen of your mind one thought passes like a cloud.
First it is vague – it is coming, it is coming – then it is there
suddenly on the screen. Then it is moving, then it has gone out
of the screen, again it becomes vague and disappears...
another thought comes. Between these two thoughts there is a
gap – for a single moment or a split second the screen is
without any thought.

That state of pure no-thought is called
hua t'ou – ante-words,
ante-thought, before the mind is stirred. Because we are not
alert inside, that's why we go on missing it – otherwise
meditation is happening each moment. You have just to see it
happening, you have just to become aware what treasure you
are carrying always within you. It is not that meditation has to
be brought from somewhere else. The meditation is there, the
seed is there. You have just to recognize it, nurture it, take
care of it, and it starts growing.

The interval between two thoughts is
hua t'ou. And that is the
door to enter into meditation.
Hua t'ou – the word literally
means "word head." "Word" is a spoken word, and "head" is
that which precedes the word.
Hua t'ou is the moment before
a thought arises. As soon as a thought arises it becomes a
hua weihua wei literally means "word tail." And then when
the thought has gone or the word has gone and there is a gap
again, it is again
hua t'ou. Meditation is looking into this hua
t'ou.
