Existence is One without a Second.

What everyone knows is that the origin of life is oneself but what few know is that oneself is without another. All is but one symbiotic whole without division. The perception of division aka the illusion of separation serves the purpose of companionship. When it is said that 'existence is One without a second' it means 'Oneself is without a second.' There is only Oneself.
