Analytical knowledge of physical body and mind

When as mentioned before, by dint of diligent practice, mindfulness and concentration have improved, the meditator (Also called as Yogavachara) will  be noticed the pairwise occurrence of
an object and the knowing of it, such as the rising and awareness of it, the falling and awareness of it, sitting and awareness of it, walking and awareness of it, bending and awareness of it, stretching and awareness of it, lifting and  awareness of it, putting down and and awareness of it. Through concentrated attention (Mindfulness) he knows how to distinguish each bodily and mental process: "The rising movement is one process; the knowing of it is another; the falling is one process; the knowing of it is another". He realizes that each act of knowing has the nature of "going towards an object". Such a realization refers to the characteristic function of the mind as inclining towards an object, or recognizing an object. One should know that the more clearly a material object is noticed, the clearer becomes the mental process of knowing it. this fact stated in the "Visuddhimagga".
For in proportion as materiality becomes quite definite, disentangled and quite clear to him, so the immaterial states that have that materiality as their object become plain of themselves too.
When the meditator comes to know the difference between a bodily process and a mental process, should he be a simple person, he would reflect from direct experience thus: " There is the
rising and knowing it; the falling and knowing it, and so on. There is nothing else besides them The words 'man' or 'woman' refer to the same process; there is no 'person' or 'soul'".
Should he be a well-informed person, he would reflect from direct knowledge of the difference between a material process as object and a mental process of knowing it, thus: "It is true that
there are only body and mind. Besides them there are no such entities as man or woman. While contemplating one notices a material process as object and a mental process of knowing it; and
it is to that pair alone that the terms of conventional usage 'being', 'person', or 'soul', 'man', or 'woman' refer. But apart from that dual process there is no separate person or being, I or another,
man or woman". When such reflections occur, the meditator must note, "reflecting, reflecting" and go on observing the rising of the abdomen, its falling etc...
