Guru Stone is a semi-floating rock located about 70 meters (230 ft) offshore Lake Toba in Pangaloan Village, Samosir. It has a diameter of about 50 meters (164 ft), a height of about 5 meters (16 ft), and a depth of about 3 meters (10 ft). It is about 1 hour from Tomok. To see it on the map, click here.
Guru Stone doesn’t touch on the lake bottom. Rather, it stands on three smaller-sized supporting rocks. Guru means teacher or master, a person with wisdom. The three supporting stones are believed to be the symbol of Batak philosophy called Dalihan Na Tolu. It consists of three messages: Somba Mar Hula-hula (respect elders), Elek Marboru (be gentle to women), and Manat Mardongan Tubu (be careful with and respectful of clan brothers to avoid misunderstanding on customs matters). These are the 3 lessons to learn from Guru Stone.
According to the folktale, once upon a time, two big stones clashed in a power struggle. The winner stood on the land, and the loser plunged into Lake Toba.
