This version of story has to do with the ‘Samudra Manthan’, the phase when gods and goddess came together to whip the drink of immortality called ‘Amrita’. A consequence of the process is the poison ‘Halahala’. The poison is considered as the most toxic that could destroy both gods and goddess and the entire universe. As soon as the poison came out it started heating up the space, which resulted in killing animals and plants. To save the entire universe, Lord Shiva emerged as a hero and ended up consuming the entire poison. Shiva didn’t swallow the poison, instead kept it in his throat. Because of the poison, his throat turned blue and hence he is called ‘Neelkantha’ or ‘blue-throated’. This resulted in causing immense heat inside Shiva and everyone was aware of the consequence of ‘restless Shiva’. Hence, efforts started pouring to calm him down.
