In Hindu mythology, Shiva is also said to have consumed Halahal, the eternal poison, to help protect the world from its evil effects. Apparently, in ancient times gods and demons tried to churn the deep seas to extract the hidden treasures in there and aside from the treasures, Halahal also came out of the churning!
This Halahal was the worst forms of poisons and threatened to destroy all that there was and gods (under Indra) approached Lord Shiva for help. Lord Shiva, being the caring deity He is traditionally viewed as, saved the universe by consuming the poisonous Halahal himself.
Lord Shiva didn't drink Halahal all the way down though; instead Lord Shiva stopped it and in a way stored Halahal in His throat. This is the reason that you might notice Lord Shiva's throat colored as dark blue in most of the Lord Shiva's pictures or statues that you see.
This little bit of mythology has many different meanings relating to Lord Shiva, Halahal poison, lowly gods and demons, the churning of the ocean and so on. The most prominent and relatively easier to understand though is the progression -
1) Beings (humans, lower gods, demons etc etc) do something.
2) The activity results in bad consequences
3) Lord Shiva saves them
Now, doesn't it kinda look like the whole christian mythology? Jesus died for human's sins and gave them another chance. In the same way, Lord Shiva took the eternal Halahal poison upon Himself to save the universe and to give the universe another chance. This parallel is uncanny and it kinda makes sense that the idea of Jesus dying for human's sins has somehow originated from the hindu mythical story of Lord Shiva drinking Halahal poison to save the world!
