You could imagine a God who is infinitely delightful. If he's the only thing in existence, he could delight in himself without end and would not be wrong in doing so, being actually delightful.
Having no limitation of knowledge or thought, he could think about himself. His thoughts would not be deficient in any detail, and thus would be an exact representation of himself. [1]
He could delight in that representation with his whole being, and that would be yet another full representation of himself. And thus he would not be alone or sad.
And he could have the propensity of emanating his delightfulness, expressing it outwards like light out of a star. And that emanation could be expressed as the creation of everything else. [2]
