Bṛhaspati (Sanskrit: बृहस्पति, often written as Brihaspati or Bruhaspati) also known as Deva-guru (guru of the gods) and Chakshas, is a Hindu[how?] god and a Vedic deity.[how?] He is considered the personification of piety and religion, and the chief 'offerer of prayers and sacrifices to the gods' (Sanskrit: Purohita), with whom he intercedes on behalf of humankind.
According to Mahabharata, sage Brihaspati was son of Angiras. Some Puranas note him to be son of Agni, the fire god. He was noted to be the guru of Gods. He was married to Tara, who was later abducted by Chandra. Tara bore a son, Budha from her abductor Chandra. After the war between Brihaspati and Chandra, Tara returned to her husband. Brihaspati's another son Kacha was assigned to learn the Sanjivani mantra from Shukracharya, the guru of asuras. The mantra could bring back life in a dead and hence gods sent Kacha to learn it. There as a student, Shukracharya's daughter Devayani, fell in love with Kacha. Brihaspati is also noted to have taught asuras for ten years impersonating as Shukracharya.
