Brihaspati (बृहस्पति) is a Vedic era sage who counsels the gods, while in some medieval texts the word refers to the largest planet Jupiter. He is the god of eloquence in some ancient post-Vedic Indian texts, and sometimes identified with god Agni. Brihaspati is one of the thousand names of Shiva.
Devayani and the son of Brihaspati, Kacha
Mention by Panini
As Guru of Devas
He was a Bhargava rishi of the Atharvan branch and a descendant of sage Kavi. The Devi-Bhagavata Purana refers to his mother as Kavyamata. The feminic natured Shukra is a Brahminical planet. He was born on Friday in the year Parthiva on Sraavana Suddha Ashtami when Svati Nakshatra is on the ascent. Hence, Friday is known as Shukravaar in Indian languages like Sanskrit, Telugu, Hindi, Marathi, Gujarati, Oriya, Bengali, Assamese, and Kannada. He went on to study the Vedas under the rishi Angirasa but he was disturbed by Angirasa's favouritism for his son Brihaspati. He then went to study under rishi Gautama. He later performed penance to Lord Shiva and obtained the Sanjivani mantra (a formula that revived the dead). He married Priyavrata's daughter Urjaswathi and they had four sons — Chanda, Amarka, Tvastr, Dharaatra and a daughter from his marriage to Indra's daughter Jayanti by the name Devayani
During this period Brihaspati became the Guru (Preceptor) of the Devas. Due to the hatred, Sukracharya bore towards Vishnu for what he perceived as the murderer of his mother as she had given shelter to some asura whom Vishnu was hunting, Shukracharya decided to become the Guru of Asuras. He helped them achieve victory over the Devas and used his knowledge to revive the dead and wounded among them.
