Ideal vision for the future vs. duality/binary reality

Can you talk about how to hold our ideal vision for the future and understanding/accepting duality? For so long I was caught up in toxic positivity/all light and love, more recently realizing the binary aspect of reality. I've been learning how to love and accept the shadow side. Now when I contemplate my ideal future for myself and humanity I'm getting caught up in the details lol I'm really confused about how our evolution mixes with the dual nature of things, I'm still learning what that even means, because of the polarity is there always going to be pain struggle and corruption? I'd love to hear your thoughts on this!

Thanks,

Nicole
