The meaning of 'I and the father are One' is that there is no division and that self is diverse not to be by itself, for companionship, for love. So I is. I and the father are One and division there is none. Diversity is Self perceived for Companionship. Love one another, there is no other, truth is one, division there is none. Otherness exists for togetherness. That which desires togetherness is Self. Self was (there in) the beginning. Self is Now. Self is always One. Oneself always is. All this for LOVE!
