This is the problem with many of these systems of understanding humans -- they don't take into account that we are animals as well as spirits. As primates whose organisms developed in a very different situation than technology has brought us to now, we have a biological need not to be alone. It's not just spiritual -- it's like, you're not going to physically survive if you are shut out of the tribe. "Being happy with myself" isn't going to protect me when the winter is cold and food is hard to find, or I am attacked by a wolf or a member of an enemy tribe or just name your life-threatening situation that you can't handle alone. And being alone doesn't make babies and assure the survival of the species. Therefore, we have a primal drive to be with others that won't go away just because I started thinking about it a different way.
And as to "negative" things being "false," well, guess what? This planet is based on death. Everything on it kills so that it may live - even sweet, innocent things like trees and plants, some of which are known to send out poisons into the ground to prevent competitor plants from springing up around it. Even vegetarians are killing and consuming living plants, not to mention all the small rodents and rabbits that are murdered every time a field is harvested. Heck, we murder thousands of small organisms every day every time we take a shower. So, let's get over the idea that we can be spirits of light floating above and untouched by all this struggle and death. All we can do is reduce the harm we cause, try to love each other, and understand that we're all in this together.
And yes, if you are a rapist and puppy eater - DO NOT BE YOURSELF, PLEASE!!! Please be very very fake, for all our sakes
