Zen meditation is the highest stage of meditation of all kind. It is not a philosophy. It was once say that Zen is evolved from Tao. Both of them shared the basic, through understanding. 

The teaching of Zen is not forceful either. Only those of you who have the wisdom and capacity to learn, to be silent, to be receptive, welcoming then you will be able to see it but not any single moment before this.

But once you are in the learning, you have to be in total, totally involved because Zen does not compromise and every action that is coming out from yourself have to be meditative. Be it, eating, walking, sleeping, bathing, whatever you do, whenever you are, has to be meditative.

The basic of Zen meditation which is  “ to move from the mind to no-mind”, which  is pure and easy to understand, existence of any level of mind is not acceptable. With Zen meditation, even the thought ”I am aware” is enough to distract you from your meditation, even the thought ”I am in meditation” is enough to destroy it. Meditation in Zen should be as innocent as it is, as silent as it is; Only thoughtlessly silence with full of awareness is acceptable.

No object shall be tolerable at all, only pure subjectivity exist. One should not even aware of nothingness, because then nothingness becomes your object and your thought. You are not supposed to be aware of emptiness either. The mirror is empty, reflecting nothing, because there is nothing to reflect.  Alertness is the one and only standard.

This is very significant. This kind of meditation has to be remained and whatever you do it always have to be there, even in death.

It is told that Zen meditation is more like a process of non-being, becoming of nothing on your own self, of disappearing from your worldly self and merging to the whole.

In the highest peak, Zen has no gap between life and death.
