What is "elunetru"

Elunetru was the object placed in the sanctum sanctorum of the worship centres of Ayyavazhi. The elunetru is a compiled structure of flame shaped copper, a saffron cloth and separate garlands made of rudraksha and Flowers. The saffron cloth in wrapped on the, perpendicularly placed flame-shaped copper, which appears like a seat, on which the separate garlands made of rudraksha and flowers are placed around. In Ayyavazhi this is which placed instead of the Idol. This was placed in the belief that we are too Knowledgeless to identify the form of God. But it is comfortable to all devotees when symbolized. And so the Elunetru, the seat was provided for the Formless God.
