The story
Dhana is wealth and teras is the thirteenth day. It is also the birthday of Dhanvantari, the physician of the gods, who rose from the churning of the ocean holding the pot of amṛta (the nectar of immortality). India's National Āyurveda Day is fixed to it.
The story told to children is of King Hima's son, doomed to die of a snake bite on the fourth day of his marriage. His wife heaped gold and silver at the door, lit lamps all round it, and sang all night. Yama came as a serpent, was dazzled by the metal and stopped to listen to the songs, and left at dawn without his prey. A lamp for Yama is still set outside the house tonight.
