A copper pot is filled with water. Mango leaves are placed in the mouth of the pot and a coconut is placed over it. A red or white thread is tied around its neck or sometimes all around it in a intricate diamond-shaped pattern. The pot may be decorated wit designs. Such a pot is known as a kalasha. When the pot is filled with water or rice, it is known as Purnakumbha representing the inert body which when filled with the divine life force gains the power to do all the wonderful things.
The Purna-Kalasha is considered a symbol of abundance and “source of life” in the Vedas. Purna-Kumbha is preeminently a Vedic motif, known from the time of Rigveda
It is also called Soma-Kalasha, Chandra-Kalasha, Indra-Kumbha, Purnaghata, Purna-Virakamsya, Bhadra ghata, or Mangala ghata.
