x1=k1 is objective / mind-independent / universal, not-varying between / existing in x2=k2=m1, in property / aspect x3=k1.
See also: mu'ecne (subjective / relative), fatci, 2 (objects and facts) defined by rules x3">facmu'e. e.g. «lonu ko'a palci cu mujykau» could be used in place of «ko'a palci fi lo fatci» to make an objective moral claim. If the universality arises from a ‘reality’ or ‘world’ ‘above’ all others, like a shared reality, or existence, even if a direct link would vary (e.g. ‘immoral according to X’), then this may be encoded in x1 or x3 - e.g. it may not be palci2 that is universal, but that «ko'a palci lo fatci» that is universal; or, perhaps a bit more simplistically, «palci zi'o» could also be talked about inside mujykau, and ma'i or a subtype of manri could bring it back. This would be like the distinction between the idea of moral universalism and the idea of moral realism. Note also that if, even though something or some claim varies, it applies universally to all members of a group, e.g. the human cultures, you can use mujykau with a restricted x2.
