According to legend, Shiva and his wife Parvati were circling the earth on a contraption made from flowers when they were dazzled by an island set in an emerald sea. Shiva, who was carrying the Ganges River on his head to protect the world from floods, decided to land. As he did so a few drops of water dripped from his head and landed in a crater to form a lake. The Ganges expressed unhappiness about its water being left on an uninhabited island, but Shiva replied that dwellers from the banks of the Ganges would one day settle there and perform an annual pilgrimage, during which water from the lake would be presented as an offering.
The dazzling island is, of course, Mauritius; the legendary crater lake is known as Grand Bassin (Ganga Talao). It is a renowned pilgrimage site, to which up to 500,000 of the island's Hindu community come each year to pay homage to Shiva during the Maha Shivaratri celebrations. This vast festival takes place over three days in February or March (depending on the lunar cycle) and is the largest Hindu celebration outside India.
The most devoted pilgrims walk from their village to the sacred lake carrying a kanvar (a light wooden frame or arch decorated with paper flowers). This is no easy feat – February is Mauritius' hottest month and it almost always rains during the festivities. Once the pilgrims arrive, they perform a puja (act of reverence), burning incense and camphor at the lakeshore and offering food and flowers.
