Budh (Mercury) in Vedic Astrology

The giver of speech

BPHS calls Mercury the giver of speech, and in the royal cabinet makes it the prince, the heir apparent: young, clever, still learning the work of rule. Its karaka roles are speech, intellect and learning, trade and accounts, writing, and adaptability. Classical lists of house significators give it the 4th house for education and the 10th for profession.

Among the tissues Mercury takes the skin, among tastes the mixed, among places the playground, among units of time a season (ritu), and among the seasons sharad, the clear weather after the monsoon.

Neuter, earthy and rajasic: the chameleon graha

Mercury is neuter, rajasic and, in the BPHS element verse, the graha of earth. Earth gives its intelligence a practical bent toward contracts, ledgers, crafts and the details of how things work, while rajas keeps it busy. Its nature is the most conditional in the system: BPHS counts Mercury a benefic, but one that turns malefic when joined with malefics. BPHS also describes it as attractive, fond of jokes, skilled with words of double meaning, and holding all three humours in balance.

Exaltation and own sign in one place

Among the seven visible grahas, Mercury alone has its exaltation and own sign in the same place. It is exalted at 15° Virgo and debilitated at 15° Pisces. BPHS divides Virgo for it: the first fifteen degrees are the exaltation zone, the next five, 15° to 20°, its mooltrikona, and the last ten plain own sign. Gemini is its second own sign. Directional strength comes in the 1st house, the east, which it shares with Jupiter, while Brihat Jataka makes it lord of the north. In a kendra in Gemini or Virgo it forms Bhadra yoga, one of the five mahapurusha yogas.

Mercury's friends, and the father it does not claim

In BPHS natural friendship Mercury counts the Sun and Venus as friends, treats Mars, Jupiter and Saturn as neutral, and counts the Moon as its enemy, although the Moon regards Mercury as a friend. The Puranic background is a family story: Budh was born of the Moon's liaison with Tara, wife of Brihaspati, and he resented that origin. Jupiter, Tara's husband, also counts Mercury an enemy, while Mercury keeps Jupiter at a cool neutral distance.

Aspect, nakshatras and seventeen years

Mercury has only the 7th-house aspect. Its nakshatras are Ashlesha, the coiled serpent star, Jyeshtha, the eldest, under Indra, and Revati, given to Pushan, protector of travellers and lost animals: a guardian, a ruler and a guide. Its Vimshottari mahadasha is seventeen years, and a separate Budh mahadasha guide on the site deals with that period.

Close to the Sun: combustion and retrograde loops

Seen from Earth, Mercury never moves more than about 28° from the Sun, so it is often combust (asta), lost in the solar glare. Many practitioners treat Mercury's combustion more lightly than that of other planets, and a Sun-Mercury conjunction even has a name of its own, Budhaditya yoga. Mercury turns retrograde about three times a year, for roughly three weeks at a time.

In transit it usually spends three to four weeks in a sign, longer when retrograde. Counted from the natal Moon, Phaladeepika makes its transit favourable in the 2nd, 4th, 6th, 8th, 10th and 11th houses, a list built mostly of even houses and one of the few that counts an 8th-house transit as good.

Upaya: practices associated with Mercury

Wednesday is Mercury's day. BPHS names Maha Vishnu as its presiding deity, so recitation of the Vishnu Sahasranama is a common practice, alongside the mantra Om Braam Breem Braum Sah Budhaya Namah. Charity of green moong, green vegetables or green cloth on Wednesdays, and of books or stationery to students, belongs to the same tradition, as do truthful speech and honest accounts. Emerald (marakata or panna) is the traditional gem association; wearing it is a personal choice that this page does not recommend, and a gem cannot replace medical, financial or legal advice.

Mercury at work: professions and learning

Tradition links Mercury with merchants, accountants, writers, editors, teachers, translators, analysts, astrologers and anyone whose craft is language or number. In the divisional charts the chaturvimshamsha (D24), the chart of learning, is where Mercury's condition is read most closely, alongside Jupiter's.

What is Mercury called in Hindi?

Mercury is Budh in Hindi, related to buddhi, intelligence. It is also called Saumya, and Wednesday, Budhvar, is named after it.

Is Mercury a benefic or a malefic?

BPHS counts Mercury a natural benefic that takes on a malefic's nature when joined with malefics. Its company in the chart therefore decides much of how it behaves.

Which day belongs to Mercury?

Wednesday. Traditional Wednesday practices include Vishnu worship, a Budh mantra, and gifts of green moong, green cloth or books to students.

What does Mercury retrograde mean in Vedic astrology?

It is the apparent backward motion Mercury shows about three times a year. Classical texts give a retrograde planet extra strength (cheshta bala), and transits during it are read with the natal chart rather than as a general warning.

What is Mercury's gemstone?

Emerald is the traditional gem association. Wearing one is a personal and traditional choice, not something this page recommends, and it is no substitute for medical, financial or legal advice.

Why is Mercury both exalted and in its own sign in Virgo?

BPHS splits Virgo for Mercury: 0° to 15° is its exaltation zone, 15° to 20° its mooltrikona and 20° to 30° its own sign. None of the other visible grahas holds all three dignities in a single sign.
