Oh ! Rama While the noble sons were reflecting over this matter, an idea flashed across their minds to get nectar by churning the Milky Ocean. [1-45-17]
Deciding upon to churn the Milky Ocean, then made Vasuki ( Thousand-headed, King of Snakes ) as the churning rope and Mt. Mandara as stirrer and those brothers whose energy was unlimited started churning the Milky Ocean thoroughly. [1-45-18]
After a thousand years, the Thousand-headed serpent Vaasuki, which was being used as churning rope,was incapacitated to bear the friction of churning and fanged the cliffs of Mt. Mandara. Thereby a great lot of venom was disgorged from the heads of that serpent Vaasuki, which venom on melting the rocks of Mt. Mandara became the holocaustic poison called haalaahala. [1-45-19]
Therefrom a lethal poison similar to inferno known as haalaahala has started to fulminate. By which the entire universe consisting of devatas, asuras and mortals was burnt down. [1-45-20]
