In Hindu mythology, Budha is the name for the planet Mercury, a son of Chandra (the moon) with Tara or Rohini. He is also the god of merchandise and protector of Merchants.
He is represented as being mild, eloquent, and having a greenish complexion. He is represented holding a scimitar, a club and a shield, riding a winged lion. In other illustrations, he holds a sceptre and lotus and rides a carpet or an eagle or a chariot drawn by lions. Budha presides over 'Budhavara' or Wednesday.
In Vedic astrology Budha is considered a benefic, unless he is joined with a malefic planet, in which case he becomes malefic also. Mercury rules over Mithuna (Gemini) and Kanya (Virgo), is exalted in Kanya and in his fall in Meena (Pisces). Budha is friendly with the Sun and Venus, hostile to the Moon and neutral towards the other planets.Budha represents intelligence, intellect, communication, analysis, the senses (especially the skin), science, mathematics, business, education and research. The written word and journeys of all types fall within his domain. Budha is lord of three nakshatras or lunar mansions: Ashlesha, Jyeshtha, and Revati (nakshatra). Budha has the following associations: the color green, the metal brass and gemstone emerald. The direction associated with Budha is north, the season is autumn and the element is earth.
