|| I worship Jupiter, the teacher of the Gods and the seers, who has the luster of gold, endowed with wisdom, the ruler of the three worlds.
Hymn to the Planet by Vyasa
Dressed in yellow, with a yellow body, who has four arms, the teacher of the Gods, peaceful in nature, whose vehicle is an elephant, who carries a rosary, a water pot and a staff in his hands, with a sapphire crest jewel on his head, making the gesture that grants boons — may Divine Jupiter ever grant us his grace.
Guru is the Vedic name for the great benefic, Jupiter. The primary deity is Brihaspati, the teacher of the Gods, who is known for his divine intellect and speech. He has reached the stage of bliss that is beyond desire. Brihaspati, the god of asceticism and the lord of speech is considered an incarnation of Brahma, the creator.
Ganapati or Ganesha is sometimes identified with the Great-Lord, Brahaspati. Ganapati is also considered as a God of Learning and “remover of obstacles”. He is the lord of categories (gana), the patron of letters and schools. Ganesha’s wives are Success (Siddhi) and Prosperity (Rddhi).
Parashara also lists Indra as the presiding deity associated with Jupiter.
