Lord Shiva
When the gods and demons churned the cosmic ocean, a deadly poison called Halahala rose and threatened all creation. Lord Shiva drank it to save the world, and Devi Parvati pressed her hand to his throat so it stayed there, turning it blue. To soothe the burning heat, the gods cooled him with sandalwood paste, which is why devotees still offer chandan to Lord Shiva.
