The first North Sumatera rituality is started with pregnancy rituality. Actually, almost all of process and methods in pregnancy rituality is same in all places in Sumatera Island. This rituality has high value for Batak Toba ethnic in their life. The pregnancy rituality is called with different name in different places, although the meaning is same; it is called Mangganje, Manghare, Mardahan, and Taor. The ingredients in this ritual have the religious meaning and wishes to Mula Jadi na Bolon (the spirit which exists there) in order to hope all of the spirits can be kind-hearted to them, and gives the blessings for Si Serep Ina (the spirit same as Mula Jadi na Bolon) and for the baby. Therefore, the evil spirit will not disrupt the baby and the mother.
After passing the pregnancy phase, it is time to bear the baby. Then, the second step is birth rituality, it is called Mangharaon rituality. In North Sumatera rituality, when mother has already born the baby, the father should drop a big wood immediately from the roof house into the yard and cut it (Manaha Saganon). The wood will be burn in the Tataring (furnace). The sound from that wood in furnace is like a signal to announce the people about the birth of baby. After that ritual, a hard situation comes, it is called Roburobuan, and it makes many people there to gather in the house of the baby.
