Phouoibi
The Phou Kouba (calling the paddy/rice) ceremony is more frequently performed in case of mis-happenings to the farmers. Mis-happenings may be theft or burning of the paddy/rice, an animal like cow trespasses the threshing ground, etc. People believe that these are all because of the absence of the goddess. So, they perform the rites and rituals to induce the goddess to stay at their places.
