Spiritually, philosophically and materially too Shiva and Shakti are immense. They together and independently manifest in different forms escaping single definition. Efforts are made here to explain their expansive cosmic natures with the help of their respective meaningful mythologies. A classic of its kind, the book will guide readers to understand primordial divinities belonging to India's religious culture with history of thousands of years, reaching Indus civilization and even far beyond it in terms of time.
