I doubt a Pythagorean would ever spare 2 words for the majority of today, outside of work circumstances. You don't lower yourself to the level of a child just to have so-called "friendship". Friendship can only come from someone who's at about the same level as you. The more distant you are, the more alienated you'll feel from each other. From people who are much below in ethics and understanding, it's like trying to make friends with a toddler. Can you? No, because the toddler is looking for playmates, not friends.
It's very similar to what the majority does today outside of work: they only play by themselves and with each other. A whole life revolving around play. Videogames, clubbing, pubs, doomscrolling, porn, hypersexuality... Someone who only engages with that outside of work is just at the same level of maturity of a toddler or a teenager.
There are some people who are beyond that and have a more balanced private and social life. Those are the people to focus on. Then there are people in-between, like a late teen trying to grow into a real adult.
Then there's small minority for which entertainment and productivity completely overlap. Not because they work in the entertainment industry but because their souls have reached that level of maturity. This excludes those new wealthy and business people who are only producing as a measure of their own ego, so they can fund a lavish lifestyle with the same level pointlessness as those who live their lives in function of play, but on steroids because they have finances backing them up. They're still children or teenagers, but with a better capability to generate wealth.
It's important to understand that it's okay for other people to live their lives at their own level of growth. Just because someone is in the next or a later stage, it doesn't mean those people should be undermined, nor should they be forced to grow. They have their own path to follow. Maybe they reach new levels of maturity in this life, maybe in the next or another life. It's up to them. You can guide them if they ask for it, but that's about it.
Souls aren't equal, nor worth the same. Find some at or around your level. For true friendship, and for love matters. ToZ provides all the tools to do that. There are also other bonds that are not friendship nor love, and don't require others to be at any specific level. Just remember that just because someone doesn't wear a ToZ tattoo or hasn't reached us yet, it doesn't mean they're necessarily bad or lower people. Normies come in all shapes and forms, at any stage.
For OP specifically, what makes you think you'd fit in Lemuria / Atlantis? We have no specific knowledge how life and people were back then. You'd need to speak to the Gods or see things with your psychic abilities to ascertain that. But it's a futile exercise if you're approaching that knowledge from the point of view of "Would I fit in there?". The past is the past. It has nothing to do with your present. Thinking that you only would fit in a past era only works to create hangups for you to fit in with people who are available NOW.
