HalÃÂhala (Sanskrit à ¤¹à ¤²à ¤¾à ¤¹à ¤²) or KÃÂlakà «á¹Âa (Sanskrit à ¤Âà ¤¾à ¤²à ¤Âà ¥Âà ¤Â, ) is the name of a poison in Hindu mythology. It was created from the Ocean of Milk when the devas and the asuras churned it (see Samudra Manthana) in order to obtain amrita, the nectar of immortality.
Fourteen different ratnas (treasures) were recovered from this episode, which were distributed between the two clans. But before the amrita could be formed, HalÃÂhala was produced, which started injuring both sides. As no one could bear the lethal fumes emitted by the poison, both the devas and the asuras began to collapse due to asphyxiation. They ran for help to Brahma who advised them to seek assistance from Shiva. Both parties went to Mount Kailash, and prayed to Shiva for help.
Shiva chose to consume the entire poison and thus drank it. His wife, the goddess Sati, was alarmed, as she gripped her husband's neck with both hands in order to stop the poison from reaching his stomach, thus earning him the epithet Viá¹£akaá¹Âá¹Âha (the one who held poison in his neck). The poison turned his throat blue. Hence, he is also known as Nëlakaá¹Âá¹Âha (the one with a blue throat).
However, according to rigveda (10.136.7) and Mahabharata Kumbakonam edition version of the legend, when halÃÂhala was produced, Vayu, the god of wind, rubbed it in his hands to reduce its potency. Then a small portion was given to Shiva, turning his throat blue. The rest was collected in a golden vessel and digested by Vayu. In another version, Vayu drank first and Shiva last. In yet another version, Shiva drank the kÃÂlakà «á¹Âa poison of the snake Vasuki, second king of the nÃÂgas, a familiar of Shiva whom Shiva blessed and often draped around his own neck as they spent time together, for it was Vasuki, stretched out stiffly, whom the gods used as the tool to turn the mountain for the churning of the Ocean of Milk.
The second episode of Indian television show Sacred Games was named Halahala based on the poison.
