 With the newly made rules of raivaru some basic rules were made on how the letters in a raivaru were arranged.Thus came into existence two main types of raivaru, first raivaru with six lines of words, the lines in a raivaru are called as "bas" so a raivaru with six lines or six sentences was called a "Ha bahuge raivaru" and the raivaru with three lines or three sentences was called as "Thin bahuge raivaru".These were merely the ground rules, Raivaru is an art so fine that in a perfectly synchronized raivaru, a lot of features and conditions have to be met .
