444. Swami Sivananda
"The Supreme Lord is represented as Siva, and His power is represented as His wife—Sakti, Durga, or Kali. Mother Durga is the energy aspect of the Lord. Without Durga, Siva has no expression; and without Siva, Durga has no existence. Siva is the soul of Durga. Durga is identical with Siva. Lord Siva is only a silent witness. He is motionless, absolutely changeless. He is not affected by the cosmic play. Durga does everything."
