The Vishukani or the auspicious sight is the arrangement of 'konna pua', a yellow laburnum flower, fruits like jackfruit and mangoes, vegetables like gourds and snake gourds, ornaments made of gold, bell metal mirror with a white, pleated cloth tied to it's handle (supposedly used by Goddess Parvati), the traditional bronze vessal'Uruli' filled with rice, items used for daily worship (asthamangalam), clothes with pure gold zari, a split coconut, some coins in a silver cup, some water in 'od ', a traditional vessal and a 'grantha', which is a palm leaf manuscript or the Bhagwat gita.
The Vishukani is prepared by the oldest member of the family the night before Vishu and the family members supposed to view it only after midnight. The kani is place in front of an image of Lord Vishnu and diyas are lit up (these are usually normal lamps but in some cases they use lamps made of coconut halves).Early in the morning of the festival, the oldest member of the family, after having viewed the kani and finished her puja, blindfolds each member of the family and sets them in front of the display.
The idea being , that all the members of the family look at the vishukani the first thing in the morning. They first look at the image, then the yellow light of the diyas and the kani in the yellow vessals.So the dominant colour of the festival is yellow. The Malayalees believe that the viewing of this display in the festival day ensures good fortune through out the coming year. The vishukani ritual is observed in the expectation of plenty in the new year.
