The ocean of Milk does not appertain to Jambu Dwipa, but it is the ocean of Saka Dwipa. The seven oceans are transformations of Prakriti, differing in the admixture of Satva, Rajas and Tamas and determining the character of the globe they surround. Vishnu, as the Third Purusha, is the divine source of evolution in every Jiva. The seat of that Vishnu is the ocean of Milk, the ocean where Satva prevails. It is Vishnu who from His seat in the Ocean of Milk sends down Prânic Energy and the mineral becomes a vegetable. He sends down the power of perception and then the power of conception and the vegetable becomes an animal and at last a man. Throughout this course of evolution, there is a development of the self element in us. There is no idea of self in the mineral or in the vegetable. It faintly asserts itself or rather makes an effort to assert itself in the animal kingdom. The early history of humanity is the development of the selfish element in him. The Jiva has two sides in himself and non-self. The self side is caused by limitation due to his own senses They put him in contact with the outside world, and make him a centre of sense perceptions. He becomes lost entirely in the sense products, which form a world by themselves. The non-self side of a Jiva, is his spiritual nature. He begins with this spiritual nature. But the development of selfishness eclipses this nature, the true, the real nature of Jiva, and he identifies himself entirely with the acquired and false nature. Then comes a crisis in the evolution of Jivas. Were men to be lost for ever to their spiritual, their real nature? Were they to be tempted away by the senses, which had done their work of training, past all chance of return? Vishnu, the God of human evolution, willed otherwise. He caused a re-adjustment of the Daivic and Âsuric forces, and the Devas by His help got the better of the Asuras. This is the churning of the Ocean of Milk. It averted a crisis and is therefore a great event in the history of the Universe. The Asura element could not be altogether wiped away. For the Deva or spiritual nature evolves out of Asura or selfish and material nature. Unselfishness grows out of selfishness, spirituality rises out of materiality. In the act of churning, the Devas could not do without the Asuras. Churning itself, implies the action and reaction of two contending forces. "Make peace with them, as long as you are not strong yourselves." The compromise of the Devas with the Asuras is the development of spiritual faculties out of the personal element in man. It is the grafting of higher Manas on lower Manas. The element of mind is in the Asuras as well as in the Devas. But the Asuric or lower mind thinks of self as separate from other selves. The Daivic or higher mind breaks through the trammels of personality and finds oneness all round. To use a better expression, we shall say higher self and lower self, rather than self and non-self.
