In order to describe the worldly relative truth, it was said:
It’s relative, delusion, when the real is masked.
Regarding as the truth what is in fact contrived
Is relative truth, this is what the sage expressed –
And that which is contrived is simply relative. (6.28)
As it obscures sentient beings’ ability to see things for what they are, it is confusion; and this condition of ignorance superimposing non-factual inherent characteristics to things, concealing the perception of the actual, is the relative (saṃvṛti). This relative causes things to be experienced as real, and that which lacks inherent nature is seen as inherently distinct. As this is relatively true for the mistaken world, it is the worldly relative truth. It is contrived interdependence.
Certain dependently arisen things, like reflections, echoes and so forth, appear as false also to the ignorant, while certain things like blueness and the like, and such things as material form, mind and feelings, appear as true. The actual does not appear in any way whatsoever to the ignorant. The latter, as well those things that also relatively are false, are therefore not the relative truth. As such, the relative truth is a principle relevant as long as one has the afflicted ignorance involved in the links of existence.
