Long ago our ancestors already knew the vagabond journey moon and stars every day. Batak is a reflection pane Parhalaan Nabolon natural law of every human being.

the time was made is usually related to the question of time is what will happen tomorrow, when a new child was born, how one’s fate, lost property and a good move for the Batak had a habit in the days of yore such as the ritual feast held everything parhalaan first open book (book Astrology).
Back to the mythological Siboru Deakparujar that twin brother of Mr. Dihurmijati Debata Sorisohaliapan is also called Panenabolon. Panenabolon in this book called Natural Law, to mark the horizon of light began to appear on the day and the evening twilight. Panenabolon according mithologi silent three-three months in one village, then move on to another village. According to modern science, that displacement is a picture of the sun, three months from the equator to the north, then three months from the equator to the North of the equator and then three months to the south and beyond three months is returning to the equator.



Panenabolon running and so on in the book, called the circulation of the universe. Way of thinking contained in the Deakparujar Siboru mythological times of circulation is the knowledge of the universe. Panenabolon journey into Toba Batak source of knowledge about time, newly enriched later with regard astrology and the moon as well as the direction of the wind.
Panenabolon shows that the source of the sun, the circulation of stars, lunar and wind direction, the growing science of the time called: Parhalaan, either the year, month, and day, and the division of time one day and one night and terms for it. relations division of time is most closely related to human life ritual. Augury that is the pattern of thinking Batak Toba General at that time. Setting a pattern that makes it so that the public thinks about the future outlook Toba Batak shifted from the original value is positive, transformed into knowledge to predict the fate of mankind.
Since mithologi Siboru Deakparujar Batak tribes in general are very fond of attention Panenabolon horizon-light visible from dusk till evening. Observed compared with a trip Panenabolon the stars at night and compares well with the circulation of the moon and the sun and the wind conditions at the time the Batak people split time.
From observation and experience, it can be seen that the circulation of the universe has something to do with life, both of human life and natural life. It means that the laws of nature had something to do with nature. Neither of human life and natural life. It means that the laws of nature had something to do with this nature, both human and animal against nature and the natural vegetation. Therefore Panenabolon and astrology as well as lunar and solar that determine the direction of the wind is very closely related to human life, then the observations for all that is most important in our daily activities.
Activities so that they can know what to do every day at the right time. So the wise men of the Batak split time in the right circumstances. If people in this western greek circulation mainly Roman transferring the universe with natural science techniques as a starting point watchmaking, the Batak people still buried in a common pattern, the circulation has not been able to transfer the techniques of the natural sciences. That is, that the division of time was still based on vision or eye observation.
