Answer: It is also necessary to develop each friend. But if you have a large group, this could be complicated because you know some and with some you do not. It is not important. Their participation in the general common work already testifies that you accept them as the people closest to you.
Imagine that every person sitting here, both men and women, are the closest particles in the huge collective soul; so we have gathered like this. I am from the previous level, you are from the next level, but all of us are connected. Imagine all the generations and incarnations, an immense soul, billions of billions of particles.
After all, each one of us is changing rapidly every second. And each time he is a new person with a new soul. The body remains the same, whereas inside of us we pass through states much faster than an electron orbits an atom. Every state is new.
From all of the states, from all of the souls, the billions of particles that there are in all the generations, we have each other—the closest. That is what we need to think about the group and that is how to relate to the friends.
