We come together for the simple reason that life, the living force, is a unifying and ASSOCIATIVE force. You are not alone in this world, because the force that created this world assiciates, not disassociates.
I think we overlook that union and coming together are natural states for us. Life is a force that brings together different parts. We know this, because without this associative aspect, nothing would hold together.
We are held together, because Life holds itself in Unity. May we quit resisting this force or making it seem more difficult than it is. We are born in Unity through the Life force that holds within Itself everything.
