I think everyone of us has a particular and personal definition of balanced and easy going, although might resemble the rest. Putting it in words is very difficult although face to face communication will give you the exact non-verbal information you need about the "balance" and "easy-going"-ness you enjoy the most.
For me a balanced person is the one that has seen many aspects of life, has seen evil and has seen good, and learnt some lessons, not from one side , but both, has a respect for all living, and knows deep down her limitations. Has an intimate awareness of her emotions and thoughts and the patterns of human behavior.
An "Easy-going" person for me is someone that gets me to a high degree and has a calm , present and acceptant attitude, and no, most people here are not like that though it may seem that way. Most people here are loaded with stuff, that's why they are here, they search for some sort of acceptance. I'm no exception from this. I can pick up people's level of consciousness pretty quickly and I tend to mirror it back at them, even on forum, choice of words provides plenty of information.
Most 8s are not easy-going in my book and god I met plenty of them. And I don't mean they are bad, is just not the best for me, that's all.
