 In order to illustrate this distinction, in his commentary [MBh] 6.28 Candrakīrti introduces the concept: mere convention (kun rdzob tsam) of the noble beings to contrast with conventionally real or conventional true (kun rdzob bden pa) of the ordinary beings. Ordinary beings erroneously grasp all conditioned phenomena as intrinsically real, therefore things are conventionally real and thus are categories of conventional truth. For noble beings, however, because they no longer reify them as real, things are perceived as having the nature of being created (bcos ma) and unreal (bden pa ma yin pa) like the reflected image ([MBh] 6.28 Dbu ma ‘a 255a).
