Guru (Jupiter) in Jyotish: wisdom and dharma
Guru (Jupiter) is the graha of wisdom, teaching and expansion, and is the karaka of children, teachers and dharma.
What it is
Jupiter owns Dhanu and Meena, is exalted in Karka, and is debilitated in Makara. Its dasha lasts 16 years. Jupiter is one of the benefics in the standard scheme.
How it is worked out or read
Jupiter gives a special aspect on the 5th and 9th houses from its own position, in addition to the seventh-house aspect shared by all grahas.
Where it appears on this site
Jupiter appears in the birth chart. The Gajakesari yoga article uses Jupiter's position from the Moon.
Jupiter's broad reach
Jupiter is the graha of wisdom, teaching, expansion and grace, and the karaka of children, teachers and dharma. It rules Dhanu and Meena, is exalted in Karka at 5 degrees and debilitated in Makara. Its dasha lasts sixteen years. Jupiter is one of the benefics in the standard scheme, and its aspects on the fifth and ninth houses are read as supportive of the themes of those houses, which are learning, children and fortune.
Jupiter and the Moon
Jupiter's position from the Moon is central to the Gajakesari yoga, which this site checks in the birth chart. The rule asks whether Jupiter is in a kendra counted from the Moon. The result is shown on the birth chart page with the rule stated. A reader who wants to understand Gajakesari should first learn the house count from the Moon and then look at Jupiter's sign.
Reading Jupiter with restraint
Because Jupiter is a benefic, readers sometimes assume that its placement always brings good results. The classical texts recognise that a benefic can be weakened, for example by a debilitation or by a difficult house, and that its strength depends on its context. A careful reading considers Jupiter's sign, its house, its lordships and the planets that aspect it, rather than its benefic label alone.
Key facts
Guru rules Dhanu and Meena, is exalted in Karka with deepest exaltation at 5 degrees, and is debilitated in Makara. Its Vimshottari period is sixteen years, and it rules the nakshatras Punarvasu, Vishakha and Purva Bhadrapada. Thursday, Guruvara, is its day. In the Puranas, Brihaspati is the teacher of the devas, and the planet's name Guru means teacher.
The twelve-year cycle
Jupiter takes about twelve years to go round the zodiac, spending about a year in each sign. Its transit is used for annual themes, and its position, together with the Sun's, fixes the timing of the great Kumbh gatherings. Jupiter turns retrograde for about four months every year. Its special aspects to the fifth and ninth houses from itself, as well as the seventh, give it a wide reach in the chart.
Reading Guru
Readers look to Jupiter for wisdom, teachers, children, wealth, faith and good counsel. It is the natural karaka of the fifth and ninth houses, and in some traditions of the husband in a woman's chart. A strong Jupiter is read as protection and growth; its aspect on a house or planet is traditionally among the most helpful influences in the chart.
