Jupiter is a fiery, noble, benevolent, masculine, expansive, optimistic, positive and dignified planet. Higher attributes of the mind and soul, generosity, joy, jubilation and joviality along with high reasoning ability and the power of right judgement are all governed by Jupiter. Jupiter rules educational interests, law, religion, philosophy, banking, economics and indicates the extent of one’s love and longing for religion, scriptures, elders and preceptors. He is also a significator of wealth, progress, philosophic nature, good conduct, health and children. Jupiter represents Thursday and the yellow colour. He is regarded as Karaka for 2^nd, 5^th, 9^th, 11^th and 12^th houses. Jupiter loses its power if these houses are occupied by his enemies. Sun, Mars and Moon are his friends, whereas Mercury and Venus are his enemies. Rahu, Ketu and Saturn adopt neutrality to him. He stands exalted in the 4th house and the 10th house is the house of his debilitation. The stone of Jupiter is Yellow Sapphire (Pukhraj). Jupiter is exalted in Cancer and debilitated in Capricorn. It rules over the zodiac signs Sagittarius and Pisces. Punarvasu, Vishakha and Purva Bhadrapada are the nakshatras ruled by Jupiter.

Jupiter provides good results if placed in houses 1, 5, 8, 9 and 12, but 6^th , 7^th  and the 10^th houses are bad placements for him. Jupiter gives bad results when Venus or Mercury get placed in the 10th house of a horoscope. However, Jupiter never gives bad results if placed alone in any house. A malefic Jupiter affects the Ketu (son) very adversely.

Worship of BRIHASPATI or GURU (JUPITER) Devata results in a cure from ailments affecting the stomach and helps one to ward off his/her sins, helps him/her in gaining strength, valor, longevity etc. He grants the boon of father-hood to the childless, good education (Vidya). He is revered as the Guru of Devas, protector of the world and is considered SRESHTA (matchless) among the wise. Kind-hearted he is considered the Loka Guru and dispenser of justice and can be known only by a proper study of the Vedas. Thursdays are considered to be the best day for the worship of Jupiter.

Jupiter in 3^rd House

The Jupiter in the 3^rd house makes the native learned and rich, who receives continuous income from the government all through his life. Saturn in the 9th makes the native live long, whereas if Saturn is placed in the 2nd the native becomes extremely clever and crafty. However, Saturn in the 4th indicates that the native will be robbed of money and wealth by his friends. If Jupiter is accompanied by inimical planets in the 3rd the native is destroyed and becomes a liability on his closer ones.

Remedies

1. Worship of Goddess Durga and offering sweets and fruits to small girls and obtaining their blessing by touching their feet. Avoid sycophants.

Jupiter in 4^th House

The 4th house belongs to Moon, a friend of Jupiter, who stands exalted in this house. Hence Jupiter here gives very good results and provides the native the powers of deciding the fate and fortune of others. He will possess money, wealth and large properties along with honour and favours from the government. In times of crisis the native will receive divine help. As he grows old his prosperity and money will increase. How so ever if he has built a temple at home Jupiter will not give the above-mentioned results and the native will have to face poverty and disturbed married life.

Remedies:

1. The native should not keep a temple in his house.

2. He should serve his elders.

3. He should offer milk to snake.

4. He should never bare his body before anyone.
