Nila Devi (or Neela Devi) is the third consort of Lord Maha Vishnu, the other two being Sri Devi and Bhu Devi.Sri devi ,Bhu devi,Nila devi are Goddess Lakshmi's Forms.In Paramapadam (Sri Vaikuntham) Sri Devi is seated to the left of the Lord (and therefore in Kausthubham, heart of Lord,in his left side), and Bhu Devi and Nila Devi to His right as Bhu Devi is first wife and Sri Devi the second wife. First wife always occupies Dakshina/Right-hand side of husband. Younger wife occupies the Vama/left hand side. The misconception of Sri Devi to right, and Bhu Devi and Nila Devi to the left arises from a common wrong equating of Sri Devi with Mahalakshmi. Mahalakshmi is singular form of all three wives mixed together. She obviously is to the right while only two forms Bhu Devi and Sri Devi are seated to his left. In such pictures, Nila is absent or indirectly present unified with Bhu Devi. Nila Devi is older than Lord and is sometimes therefore called Jestha Devi, when Vishnu is called Lord Shani. So even though she is third wife, being older in age occupies right side of Lord along with Bhu Devi. Nila is basically Bhu Devi modified and both are symbol for patience and burden. Nila Devi is embodiment of simplicity of Lord Vishnu. Bhu Devi is embodiment of the rule of the lord on earth. While Sri Devi is embodiment of Grandeur of the lord. The Veda sings the glory of Goddess Nila in Nila Suktam.
