Rigveda Traditionally, the earliest mention of the vajra is in the
Rigveda, part of the four
Vedas, though inscription wise, the earliest mention is being part of the name of a Javanese king. It is described as the weapon of
Indra, the chief among the
devas. Indra is described as using the vajra to kill sinners and ignorant persons. The Rigveda states that the weapon was made for Indra by
Tvaṣṭṛ, the maker of divine instruments. The associated story describes Indra using the vajra, which he held in his hand, to slay the asura
Vritra, who took the form of a serpent. In the context of Rigvedic weaponry, the word vájra appears to have been used for the sling as a weapon, but also for extremely effective sling projectiles specially crafted from lead corresponding to cast lead projectiles as they were in widespread use in the cultural areas of the Middle East and the ancient world, especially in classical antiquity. On account of his skill in wielding the vajra, some epithets used for Indra in the Rigveda were
Vajrabhrit (bearing the vajra),
Vajrivat or
Vajrin (armed with the vajra),
Vajradaksina (holding the vajra in his right hand), and
Vajrabahu or
Vajrahasta (holding the vajra in his hand). The association of the Vajra with Indra continued with some modifications in the later Puranic literature, and in Buddhist works.
Buddhaghoṣa, a major figure of Theravada Buddhism in the 5th century, identified the Bodhisattva
Vajrapani with Indra.
Puranas of King
Vajiravudh of
Thailand Many later
puranas describe the vajra, with the story modified from the Rigvedic original. One major addition involves the role of the Sage
Dadhichi. According to one account,
Indra, the king of the
devas, was once driven out of
Devaloka by an
asura named
Vritra. The asura was the recipient of a boon whereby he could not be killed by any weapon that was known till the date of his receiving the boon, and additionally, that no weapon made of wood or metal could harm him. Indra, who had lost all hope of recovering his kingdom is said to have approached
Shiva, who could not help him. Indra, along with Shiva and
Brahma, went to seek the aid of
Vishnu. Vishnu revealed to Indra that only the weapon made from the
bones of
Dadhichi would defeat Vritra. Indra and the other devas, therefore, approached the sage, whom Indra had once beheaded, and asked him for his aid in defeating Vritra. Dadhichi acceded to the devas' request, but said that he wished that he had time to go on a pilgrimage to all the holy rivers before he gave up his life for them. Indra then brought together all the waters of the holy rivers to
Naimisha Forest, thereby allowing the sage to have his wish fulfilled without a further loss of time. Dadhichi is then said to have given up his life by the art of
yoga after which the devas fashioned the vajrayudha from his spine. This weapon was then used to defeat the asura, allowing Indra to reclaim his place as the king of Devaloka. Another version of the story exists where Dadhichi was asked to safeguard the weapons of the devas as they were unable to match the arcane arts being employed by the asura to obtain them. Dadhichi is said to have kept at the task for a very long time and finally tiring of the job, he is said to have dissolved the weapons in
sacred water which he drank. The deva returned a long time later and asked him to return their weapons so that they might defeat the asura, headed by Vritra, once and for all. Dadhichi however told them of what he had done and informed them that their weapons were now a part of his bones. However, Dadhichi, realising that his bones were the only way by which the deva could defeat the asura willingly gave his life in a pit of mystical flames he summoned with the power of his austerities. Brahma is then said to have fashioned a large number of weapons from Dadhichi's bones, including the vajrayudha, which was fashioned from his spine. The deva are then said to have defeated the asura using the weapons thus created. There have also been instances where the war god Skanda (
Kartikeya) is described as holding a vajra.
Ramayana According to the
Ramayana, as a child,
Hanuman grew to enormous proportions, and attempted to swallow the sun, regarding it to be a ripe fruit. He also attempted to devour
Rahu, who had been divinely assigned the function of swallowing the sun. Furious, Rahu pleaded his case to
Indra, who immediately appeared to the scene upon his elephant mount,
Airavata. When Hanuman attempted to seize his mount, Indra retaliated by striking Hanuman's chin with the vajra. Hanuman fell toward the earth, where the child's spiritual father and god of the wind,
Vayu, caught him before he crashed upon the ground, and withdrew with him to a cave. In retaliation, he called upon all of the air that permeated creation, causing the suffocation of all life in the universe.
Brahma, the god of creation, summoned a number of deities to the cave to placate Vayu. Indra imbued the limbs of Hanuman with the power of his celestial thunderbolt. ==Vajrayana Buddhism==
