Each practitioner has to SIT DOWN, facing his/her personal Wall, and LOOK at it.
Sitting down means STABILIZING YOUR MIND.
FACING THE WALL means to FOCUS on your own mind, as the object of concentration.
LOOKING means PENETRATING the Wall.
If you are skillful enough, you don´t need to physically sit down. You can "SIT" while walking. As long as you are able to keep a peaceful mind, you are SITTING.
Facing the wall means to keep your attention on your own mind.
Mind here means the SKANDAS.
Unless you focus on them, you will never know the root of suffering, and consequently, the wheel will keep turning.
Looking means penetrating, using INSIGHT to SEE the real nature of the wall.
If you don´t know how to Sit down your mind, you better find a master who can teach you. But remember that sitting is not enough.
After sitting, you have to face your wall and look at it.
Analyzing is not looking.
Thinking is not looking.
In fact, in order to SEE, you will have to CRACK your INTELLECTUAL MIND.
When you SEE, that is SATORI.
SEEING THE NATURE OF MIND IS SATORI.
But SATORI is not enough. You have to familiarizate yourself with it: that is REALIZATION.
Don´t fall asleep, or you will find the Kyoshaku on your back.
