A man is a complex whole of nama (mind) and rupa (matter). Mind by its nature is conscious. Matter is unconscious. The two are diverse in their nature. There is no possibility of congenial mutual understanding between such contradictory things in nature. Moreover, there remains harmonious functioning and mutual understanding in them. It is interesting to note that while mind and matter are mutually conditioning and interact, they are still separate things. There is clear distinction between dhammas, which are part of mind (nama) and those, which belong to matter (rupa). Further, the life duration of rupadhamma is sixteen times more than that of a namadhamma. The relation between rupadhamma and namadhamma has been explained with simultaneous fall of leaves and fruits from a tree. Thus, life duration of the rupadhamma is much longer than that of the namadhamma. This mind-matter relationship has been analyzed.”, in the texts of Abhidhamma Pitaka, its commentaries and manuals of Abhidhamma through twenty-four types of relations (paccayas), which are considered as ‘energy’, dynamic in nature.
