Creation of Asi

The devas approached Brahma, the creator of the universe, in ancient time and protested against the unjust rule and evil doings of the demons (danavas). Hearing the protest from the deities, Brahma collected sacrificial objects and proceeded to perform a grand sacrifice with the foremost of the rishis and devas at the side of Himalaya.

During the course of the sacrifice, a dreadful creature sprang from the midst of the sacrificial fires scattering flames all around. It was as though a moon had arisen in the midst of the stars. He was coloured like a deep-blue lotus. His teeth were sharp and terrible, stomach lean and skinny and stature very tall and slim. He was of exceeding energy and power. Simultaneously the earth started shaking, there were turmoils in the oceans, the forceful winds started howling all around, the trees started falling and being torn apart and the meteors started blazing through the skies, Brahma declared

The 'being' I have conceived is Asi. It shall effect the destruction of the enemies of the gods and restore the Dharma

Upon this, the creature assumed the form of a blazing sharp-edged sword, glowing like flames. This sword was the primordial weapon created by the deities for the destruction of evil. The name of the sword was Asi, the personification and the primary energy behind all weapons ever created. As per Bhishma, the constellation under which the sword was born is Krittika, Agni is its deity, Rohini is its Gotra, Rudra is its high preceptor and whoever holds this weapon obtains sure victory and have absolute power over any weapon ever created since asi is the primordial source of energy behind all weapons.^[1]

Brahma gave that sword to Shiva and requested him to put down the sinners and evil-doers and restore the Dharma (righteousness). Shiva assuming his terrible form, took up the sword and started the war against the Danava's, the enemies of the Deva's. The earth became miry with flesh and blood of daityas and he destroyed the entire community of daityas.
