How to practice satipatthana?

Question : How should we practice in the right way satipatthana, and in
particular Mindfulness of Body?
Answer : There are six doors of the eyes, ears, nose, tongue, bodysense and
mind. The objects presenting themselves through these six doors constitute
the "world" which appears to us; in fact there are six worlds appearing to the
six doors. If there were not those six worlds we would not experience
anything. At this moment there is seeing, but one may not know seeing as it
is: only a type of reality, a kind of experience, different from thinking or
hearing. What appears through the eyes is visible object, and this is different
from sound.
The person who realizes the truth at the moment of seeing, hearing, smelling,
tasting, experiencing tangible object or thinking, will not have any doubts
about the four Applications of Mindfulness: Mindfulness of Body, of Feeling, of
Citta and of Dhammas. There may be doubts about the names of the four
Applications of Mindfulness, about concepts, but not about realities. The
person who realizes the truth knows that there are realities of the body,
rupas, which are appearing time and again. The rupas appearing all over the
body, from head to toes, are dhammas, realities. Citta can experience the
reality which appears through the bodysense when the body is touched.   
It is difficult to eliminate the wrong remembrance of self. when the rupa
which is cold impinges on a certain part of the body, it falls away
immediately, but it is difficult to realize this. There is still remembrance of, "It
is I who is sitting", there is still remembrance of arms, legs, head, of the body
as a whole. The wrong view of self has not been eradicated. The Buddha
explained that, when sati arises and is aware of the characteristic of the
reality which is appearing, one at a time, through the bodysense, there is at
such a moment the Application of the Mindfulness of the Body. The Four
Applications of Mindfulness are not something else but mindfulness of what
appears through the eyes, the ears, the nose, the tongue, the bodysense or
the mind.
People should not select the object of mindfulness, because then there is
clinging to an idea of self who can select such an object. Nobody can direct
sati to a particular object, it is sati itself which is aware of such or such
object.  Sati can be aware of what appears through the eyes or of seeing at
this moment when there is seeing. At such a moment there is not Mindfulness
of Body. There can be Mindfulness of Dhammas or Mindfulness of Citta,
depending on conditions. There is no method which tells one to do particular
things in order to have Mindfulness of Body, of Feeling, of Citta or of
Dhammas. There is no method at all to be followed. The only way to develop
satipatthana is to gradually understand the realities which are appearing. Sati
can be aware of whatever reality is appearing. For example, when there is
seeing, there may be awareness of feeling. When there is awareness of the
characteristic of feeling, there is at that moment not Mindfulness of Body or
Mindfulness of Citta. The Pali term used in this context is vedananupassana
satipatthana, meaning: consideration or observation of feeling. This shows
that panna develops by being mindful, by considering the characteristics of
realities. If people never are aware of the characteristic of feeling, they will
continue to take feeing for self.
