52) Śiva-kāmeśvarāṅkasthā
Lalitā resides in the lap of Śiva-Kāma-Īśvara. She is eternally coupled to him. Kāma means desire, or the generator of desire, Manmatha. Śiva, when he has erotic desire, becomes Kāma, or Manmatha. This Kāma is unparalleled in his ability to assure infinitely different forms. God became many forms through his desire to experience his capabilities. As wife of Kāma, Lalitā is Ratī Devi Herself; the word Ratī meaning erotic love and coitus. The Vedas declare thus: the source of the heart, mind, intelligence, intuition, discrimination, analysis, learning, sight, memory, decision, sacrifice, life, and control is the one and only eros, Kāma. This Kāma is also pious, generator of bliss and the controller of the world, Īśvara. Thus Lalitā rests in the lap of Śiva (bliss) - Kāma (erotic love and its higher expressions) - Īśvara (control). She is the sum total knowledge of this and other worlds, She is the knower of these worlds, and She is these worlds. This is the meaning of the eternal coital symbol of Śiva liṅga. The knower is the Yoni. The knower is Śiva. Knowledge of being is the bliss.
