Vritra was killed by a weapon made of the bones of Dadhîchi the Rishi of self-sacrifice. We want to kill thee for thy bones, for they will be of service to the universe, so said the Devas. And Dadhîchi felt the height of pleasure in giving himself completely up, that the universe might prosper. We are told that the fight with Vritra took place in the Vaivasvata Manvantara. The readers will easily understand why this is so. The fight between the Devas and the Asuras is only a counterpart of struggles on our earth between the forces of materiality and spirituality. With the appearance of Lord Krishna, the ascendancy of the Asuras is virtually over, and however self-seeking we may be by our nature, we bow down before the ideal of unselfishness, of One Life pervading all beings, so prominently held before us by that greatest of all Avatâras, and the circle of those that follow this ideal is daily increasing. But why is Atharva Veda spoken of as the Veda of unselfishness? The popular idea about that Veda is quite the contrary. People resort to it for Tântric malpractices. The Vajra or thunderbolt is an electric current, which in the hands of Indra has the power of spiritualisation. The Asuras dread the subtle forces of nature which reach them even in the regions of Pâtâla. Who knows what purpose the electric discharges serve in the economy of nature? Who knows of the subtler currents of spiritual forces that silently bring about the grandest revolutions in nature? Atharva Veda inculcates an intimate acquaintance with the subtle forces of nature. It opens the door alike to White as well as Black Magic. But at the present day, the Black Magic only survives, making the Atharva a name of opprobrium and reproach. Marut is Vâyu. The Maruts are forms of Pranic energy. They are 49 in number, corresponding to the 49 forms of Agni. These 49 forms include all sorts of Pranic energy in the spiritual, intellectual and material planes. As the whole process of evolution is dependent on life activities, and as life itself is essentially divine, the Maruts are the companions of Indra. As by life, we understand individual life as imprisoned in Jivic centres, the Maruts are by birth Daityas.
