Of course all that is here is Self desiring not to be by itself. It is why diversity exists. Diversity exist not to feel alone. Diversity exists for Companionship. Diversity exists for Love. The purpose is not to fight, quite the contrary, the purpose is Companionship otherwise known as Love.

The origin of the universe is (the awareness of) loneliness and the purpose of the universe is companionship. All this for love, so not to be alone.

Self appears as many but all the many are Self. Self appears as many not to be by itself. Self appears as many for Companionship. Self appears as many for Friendship. Self appears as many to Love and be Loved in endless return.

There's a couple of different realizations. Perhaps the first realization is Aham Brahmasmi. Then perhaps the following is realized. Before Abraham I AM. Then perhaps the following is realized. Before Brahman ॐ. As such it is realized ॐ. But it doesn't stop here for what really matters is Love. You see. Why does Self (I) perceive itself as diversified? Diversity exists not to be alone. Diversity exists for Companionship. Diversity exist for Love. Love is Terminus Ad Quem.

All is One, Division there is None.

Does the human brain create its own reality? It is correct that everybody lives in their own reality bubble. But to be more precise. Reality is one, bubbles are many. At any time, there is only oneself leaving space between itself so not to be by itself. What does it mean? Self has created the bodymind complex so not to be by itself. The purpose of self is companionship. Love so Love.

The most amazing fact about the universe is that the universe is self differentiated for companionship, friendship, love. Although the above is correct it remains an abstraction. Truth is simpler yet. The universe is self and self is differentiated so to love and be loved in return.

The highest wisdom is knowing there is only Oneself and that the perception of otherness exists for companionship alone.

Life is self expressing itself as self-differentiated for the purpose of companionship, friendship, love.
