Guru

Guru is Jupiter, and the name means teacher. The Brihat Jataka also gives Jeeva, Angirasa, Vachasampati and Ijya, and calls it Suraguru, the preceptor of the Devas. In the Kalapurusha, the book's zodiac-body, it is knowledge, and it is a counselor in the court of the planets with Venus. The text pictures a big body with yellow hair and eyes, and links it to ether, the north-east, a sweet flavor, and the winter months of November and December.

Dhanu and Meena belong to Jupiter. Cancer is its exaltation, at the fifth degree, and Capricorn its fall at the same degree. Sagittarius is its mulatrikona, a favored strong sign, and the Sanskrit Brihat Parashara Hora Shastra as typed on Wikisource, from an unidentified edition, puts that stretch at the first 10 degrees. The stanza on Jupiter's friendships names Mercury and Venus as enemies and Saturn as neutral, which leaves the Sun, the Moon and Mars as friends.

Jupiter sees the fifth and ninth houses fully, on top of the seventh that every planet sees, and the typed chapter 26 of the same Sanskrit book agrees. According to Varahamihira, the rising sign gains strength if occupied or looked at by its lord, by Jupiter or by Mercury. Jupiter has strength in the east and by day, and in the Vimshottari scheme it rules 16 years, over Punarvasu, Vishakha and Purva Bhadrapada.
