The purpose of Self is Companionship.

The answer to the question - is space a vacuum? - is unanswerable. Space is not space; space is Self. Is Self the void? That which is Śūnyatā is Self. Self does not like to define itself as Non-Self for there is only One-Self. What is Self? Self cannot define itself in words but the collective output as that which Humankind calls reality is Self. What is the purpose of Self? Self likes Companionship. Self does not like to be alone. The purpose of Self is Companionship.
