The ego exists for Companionship.

It is said that the ego seeks to divide whereas spirit seeks to unify. The truth is less complex. The ego exists for companionship. Companionship is the purpose and aloneness is the cause. Existence is One. One is Self. Self is undivided but perceives itself as divided not to be alone. Simply put; the cause why Oneself perceives itself as different egos is the desire not to be alone which equates to the desire for Companionship, Friendship, Love. In other words; there is only One Self, i.e., Oneself. Oneself seeks to negate its own aloneness through the illusion of separation. The illusion of separation serves but one purpose; Companionship. Companionship is a synonym for Love, Friendship, Togetherness. All this (Life) not to be alone; for Love!
