Kalasha is a metal (usually made of copper) vessel with a flat, round base and is used in many Hindu rituals. Kalasha is also known as Kalasha, Kalasa, Kumbha, and Ghat. Kalasha symbolizes abundance and prosperity in Hinduism. It is also used as a symbol on wedding cards to show a marriage between two families. Kalash is a sacred symbol for Hindus. A Kalash is generally placed in or near a Hindu altar and is worshipped during daily Pujas.

During the time of rituals, the Kalash is filled up with water up to the neck of the vessel and five leaves of mango and/or Nagin plant are kept at the opening of the vessel in such a way that the leaves immerse partially in the water. Some coins are placed inside the vessel. A swastika is drawn with Kumkum on the front portion of the vessel. After this, a coconut is placed on the top of the Kalash. A garland of flowers is also placed around the Kalasha.

Kalasha is worshipped mainly during Vastushanti, Grihashanti, Navratri, marriage ceremony, and other important auspicious occasions.

References to the Kalasha can be found in the Rigveda. Also, it is believed that Amrit (the drink of immortality) was found in the Kalasha during Samudra-Manthan. The demons stole this Amrit-Kumbha, but the gods took it back and drank all the Amrit.

Kalash is also considered auspicious in Jainism.
