Kaliya कालिय, in Hindu traditions, was a poisonous Nāga living in the Yamunā River, in Vṛndāvana. The water of the Yamunā for four leagues all around him boiled and bubbled with poison. No bird or beast could go near, and only one solitary Kadamba tree grew on the river bank. The celebration of Nāga Nathaiyā or Nāga Nṛitya is associated with the tale of Lord Krishna dancing upon and subduing Kāliya.
