A kalasha, also spelled kalash or kalasa (Sanskrit: कलश; kalaśa, literally "pitcher, pot"), is a metal (brass, copper, silver or gold) pot with a large base and small mouth, large enough to hold a coconut. Sometimes "Kalasha" also refers to such a pot filled with water and topped with a coronet of mango leaves and a coconut. This combination is often used in Hindu rites and depicted in Hindu iconography. The entire arrangement is called Purna-Kalasha (पूर्णकलश), Purna-Kumbha (पूर्णकुम्भ), or Purna-ghata (पूर्णघट). Each of these names literally means "full or complete vessel" when the pot is referred to as the Kalasha (to avoid confusion, this article will refer to the pot as Kalasha and the entire arrangement as Purna-Kalasha). Sometimes the Kalasha is filled with coins, grain, gems, gold, or a combination of these items instead of water. The coronet of 5, 7, or 11 mango leaves is placed such that the tips of the leaves touch water in the Kalasha. The coconut is sometimes wrapped with a red cloth and red thread; the top of the coconut (called Shira – literally "head") is kept uncovered. A sacred thread is tied around the metal pot. The Shira is kept facing the sky.
