Srimad Bhagavatam

"The creation, preservation, and dissolution of the universe are all divine play. In the universe, the Self, who is the Self of all beings, appears as many. Before creation, and in dissolution, the world exists as one absolute existence, which is God. Then there is neither the seer nor the seen, neither subject nor object. There exists only consciousness itself. In that consciousness, which is the absolute God, is the power which divides itself into the seer and the seen, the cause and the effect. This power is called Maya."
