Unity of among diversity is seen in the festival of Bihu. Assam consists of various different unique tribes who have their precise own traditions and culture. In spite of such diversity they are all United in celebrating the festival.
As I could focus only on one aspect of the festival I have chosen the first day of the festival of Bhogali Bihu. Many different customs and rituals are followed on that day. Starting by taking the cattles(read cows) to the river and giving them a bathe , then cut pieces of vegetables like Bottle groud , brinjal etc are thrown at them as a sign of blessing towards them. The Cattle sheds are cleaned and new harnesses for the cattle are brought. After that one have to take bath by applying a paste of raw turmeric and lentil paste of their body.
Several different dishes are served on that day owing to the rituals.The most interesting among them is a dish cooked with one hundred different herbs. Second on the list is red ants larvae . You could even find silkworms. Chicken, Duck , Pork are eaten by choices. One thing that every household shares in common is rice soaked overnight in water. A bowl of brewed rice wine is not be forgotten .
Later in the evening everyone gathers together and dance , eat , enjoy to the tunes of Bihu hymns. This festival marks the starting of the rice cultivation season . After the festival everyone heads to the fields and this marks the beginning of the rice cultivation.
