'The Wavy waters in the picture are symbolic of Karma; and lotus, of Bhakti; and the rising-sun, of Jnana. The encircling serpent is indicative of Yoga and the awakened Kundalini Shakti, while the swan in the picture stands for the Paramatman (Supreme Self). Therefore the idea of the picture is that by the union of Karma, Jnana, Bhakti, and Yoga, the vision of the Paramatman is obtained.'          -- Swami Vivekananda
