In the ancient times the devils and gods tried to make ambrosia from stirring the sea water. Initially the poison emerged out and it was not able to stir the ambrosia. Here Maha Vishnu asked the help of Lord Shiva and he agreed to drink this poison. This is the place where he drank the poison and his wife Parvathi caught his neck by her hand so that the poison may not enter inside his body. Very soon his throat area becomes blue in color because of this poison. Since then he was called NeelaKhantan or the person with blur color throat. After this event the demons and the gods were able to stir ambrosia from the sea and it was transported by the Garuda a kind of vulture to Kailas Mountains for Lord Shiva.
