I am interested in understanding stages from Amber downward better. I read Integral Psychology plus some shorter documents from this website, and I will probably get some more Integral books soon.
Can anyone recommend books or other resources that illustrate the perspectives of Amber and below with real-world examples [EDIT: from around the world ideally] and explore the ideas a little more deeply than general descriptions of the stages? I am interested in this both at the societal and personal scale to understand my own hangups there better but also especially to better understand people I may be interacting with from very different cultures that may be closer to these levels.
Thanks and happy New Year!
