Among the Karo and the Toba there are sometimes widely diverging versions of where the "tendi" dwells and how many "tendi" there are. According to the Toba a person has seven "tendi". The second "tendi" is found in the placenta and amniotic fluid of the new-born baby, and accordingly the afterbirth is given special attention after the birth of a child. It is usually buried under the house, is called "saudara" (brother) and is regarded as the person's guardian spirit. Similar ideas about the afterbirth are also found among the Karo, who also bury the placenta and amniotic fluid under the house and regard them as two guardian spirits ("kaka" and "agi") who always remain close to the person.
