I know that there is what is described as universal True Nature - aspects common to everyone. I know about Karma, which can be seen as how beings have tendencies even from birth (which otherwise has no explanation that I can see). This question is whether each person (regardless how you think they exist or not) has a particular set of characteristics that are theirs to express in living their full potential?
Buddhism is sometimes accused of being nihilistic in the way that it seems to leave no reason for people to function when they overcome ignorance and realize the truths. This is your chance to explain, using references, that no, every person is a valid and necessary part of the complex web of Experience, not just a wrinkle that escaped temporarily from The Void.
