Vishu is celabrated as a New Year in Kerala in the Month of April. The main ritual on this day is Vishukkani. It is believed that the first objects which one sees on the morning of Vishu determine the prosperity experienced in the coming year. As a result, people make it a point to see all the auspicious things as soon as they wake up. A special ritual arrangement of auspicious articles like raw rice is put in a circular bell-metal vessel known as 'Uruli' and over it a folded newly washed cloth is spread. A golden coloured cucumber, betel leaves, betel nuts, metal mirror, yellow flowers of Konna tree (cassia fistula), a few gold coins are then placed over the cloth in the vessel. Then some oil is put into two coconut halves, a few wicks are lit and this illuminates the goodies inside. A bell metal lamp called nilavilakku is lighted near it.
