Letters of Sri Aurobindo
6. The Divine and the Hostile Powers
Fragment ID: 607
Shiva is the Lord of Tapas. The power is the power of Tapas. Krishna as a godhead is the Lord of Ananda, Love and Bhakti; as an incarnation, he manifests the union of wisdom (Jnana) and works and leads the earth-evolution through this towards union with the Divine by Ananda, Love and Bhakti.
The Devi is the Divine Shakti – the Consciousness and Power of the Divine, the Mother and Energy of the worlds. All powers are hers. Sometimes Devi-power may mean the power of the universal World-Force; but this is only one side of the Shakti.
