Two days prior to Deepawali, on the 13th
day of dark half of Kartik, Dhan Teras or Dhanvantri
Triyodashi is observed with great mirth and gaiety.
Dhanvantri, the physician of gods, who appeared at
the churning of the ocean, is worshipped on this
day, especially by the physician-community. He is
the father of the Indian medical science and
Ayurveda is attributed to him. He is also called
Sudha-pani, because he appeared from the ocean,
carrying nectar in his hands.
The people get early at dawn, cleanse
themselves put on new attires and observes fast. In
the evening an earthen-lamp is invariably lit before
the door of every house, and the fast is broken. New
utensils are bought on this day because it is
regarded very auspicious.
