One such mesmerizing thing that emerged was the Halahala (deadliest poison) from the sea. It is clearly written in various sacred texts that this venom was so lethal that it could have destroyed the entire universe. In such a scenario, the merciful Lord Shiva decided to drink it to save the creation. However, when Goddess Parvati saw him taking poison, she at once held His throat so that the deadliest poison wouldn’t go down further.
