Mirror and information? Listener question

You remind us that because we see everything through the lens of our own conditioning then how people appear to us isn't objectively true. This is part of why inquiring about how someone else is a mirror of our own behaviors is so powerful.You also remind us to look for information/truth in what people say to/about us. Is that because the things they say are still screened through our conditioning? Or is it because relative truth delivered from apparently someone else is still valuable?
