We create energy with our common actions of unity. But we also need to properly use it for everyone to unite with the group.
The energy that I receive from the group is my reward for being loyal to the group. I become an integral part of a whole to the extent of my loyalty; I am prepared for them to do whatever they consider necessary to me.
This means that I use the group correctly and I can continue to demand energy from it in order to become even closer to it.
I give myself without a thought that they will fill me with their values and then this part becomes incorporated into the mutual guarantee without a doubt.
