If we take the somewhat conflicting passages referred to above for our consideration and try to combine them so as to understand what is meant by rûpa, I think we find that that which manifested itself to the senses and organs was called rûpa. No distinction seems to have been made between the sense-data as colours, smells, etc., as existing in the physical world and their appearance as sensations. They were only numerically different and the appearance of the sensations was dependent upon the sense-data and the senses but the sense-data and the sensations were "rûpa." Under certain conditions the sense-data were followed by the sensations. Buddhism did not probably start with the same kind of division of matter and mind as we now do. And it may not be out of place to mention that such an opposition and duality were found neither in the Upani@sads nor in the Sâ@mkhya system which is regarded by some as pre-Buddhistic. The four elements manifested themselves in certain forms and were therefore called rûpa; the forms of affection that appeared were also called rûpa; many other mental states or features which appeared with them were also called rûpa [Footnote ref 2]. The âyatanas or the senses were also called rûpa [Footnote ref 3]. The mahâbhûtas or four elements were themselves but changing manifestations, and they together with all that appeared in association with them were called rûpa and formed the rûpa khandha (the classes of sense-materials, sense-data, senses and sensations). In _Sa@myutta Nikâya_ (III. 101) it is said that "the four mahâbhûtas were the hetu and the paccaya for the communication of the rûpakkhandha (_rûpakkhandhassa paññâpanâya_). Contact (sense-contact, phassa) is the cause of the communication of feelings (_vedanâ_); sense-contact was also the hetu and paccaya for the communication of the saññâkkhandha; sense-contact is also the hetu and paccaya for the communication of the sa@nkhârakkhandha. But nâmarûpa is the hetu and the paccaya for the communication of the viññânakkhandha." Thus not only feelings arise on account of the sense-contact but saññâ and sa@nkhâra also arise therefrom. Saññâ is that where specific knowing or _________________________________________________________________ [Footnote 1: _Sa@myutta Nikâya_, III. 86.] [Footnote 2: _Khandhayamaka_.] [Footnote 3: _Dhammasanga@ni_, p. 124 ff.] 96 conceiving takes place. This is the stage where the specific distinctive knowledge as the yellow or the red takes place.
