The Divine wants to play, because just resting as absolute unmanifest bliss gets a little boring. God wants to thicken the plot. So Shiva manifests our bodies as his players through the Lila-Shakti of Divine Mother. Lila-Shakti literally means "Play-Power."
Likewise in the Western tradition, She is Sophia-Wisdom (Hochma in Hebrew). God does not create the world without her help, her delight, and her play. Of course the Lord and Sophia are not two, they are one. But the one plays as two. THE ONE PLAYS AS TWO. This is lila-shakti.
The Biblical book of Proverbs personifies Wisdom as the Divine Feminine, God's consort, singing ecstatically:
"I was established from everlasting, from the beginning, before the earth was. When there were no depths, I was brought forth... while as yet he had not made the earth, nor the fields, nor the beginning of the dust of the world. When he founded the heavens, I was there; when he set a circle upon the face of the deep. Then I was by his side, as one brought up with him; and I was daily his delight, rejoicing always before him..." (Proverbs 8)She is God's first playmate. She creates us from her whirling. Through Shakti's joyful Wisdom-energy, Shiva gets innumerable dance partners, clothed in moonlight or cloud, raindrop or sunbeam, Winter, Spring, abundance, poverty, pain or laughter.
Thank you Mother for this body, God's flute, and your breath inside it. Thank you for these seven golden cups overflowing with wine. Thank you for all my wounds, streaming with Light.
