Parallels of Bihu among the other races and tribes of Assam are Baisagu for Bodo Kacharis, Baikhu for Rabhas, Ali- Ai -Ligang for Misings, Bohhaggio Bishu for Deoris. Contemporaries of Magh Bihu are Nara-siga Bihu of Miring, Pushy Par or Tushu Puja of tea tribe of Assam. Other community festivals of Assam are Rongker of Karbis, Rajini Gabra and Harni Gabra of Dimasa tribe. The Bohag Bihu is celebrated in different other forms in different parts of India. In Punjab, it is celebrated as ‘Baisakhi’ and likewise other places have other forms.
The Rongali Bihu is celebrated for around a month with different festivities going on throughout the Bohag month. The people celebrate this festival with merriment and joy. The feasting starts and farmers prepare the fields for cultivation of paddy. Delicacies like pitha, laru, jolpan (traditional food made predominantly with rice) are prepared by the womenfolk. Rongali Bihu is a time of merriment and feasting and continues, in general, for seven days.
The first day of the Rongali Bihu is the Goru or Cow Bihu. On this day, the cows are washed and worshiped. This day falls on the last day of the previous year, usually on April 14. The cattle are smeared with turmeric paste, bathed in rivers and canals and are the let to stray. The cattle are washed, smeared with ground turmeric and other pastes, struck with sprigs of dighalati and makhiyati and endeared to be healthy and productive. A hearty meal of gourd and brinjal is fed to the cows, while singing the Assamese traditional song (lao kha, bengena kha, bosore bosore barhi ja / maar xoru, baper xoru, toi hobi bor bor goru) which means eat gourd, eat brinjal, grow from year to year / your mother is small, your father is small, but you be a large one).
In the evening when the cows return home, the old cattle bindings are cast away and new ropes are used. They are worshiped and well fed on that day. The Goru Bihu or cattle worship rites are observed on the last day of the year. The rationale behind the worshiping of cows is very simple. They are the greatest assets of a farmer because not only do they produce milk but also help plough fields, transport men, crop and so on.
