Guru of Shukracharya

Shukra, also know as Shukra, is the son of the great sage Bhrigu and Ushana, daughter of HiranaKashipu. He went to the hermitage of Angirasa to learn the scriptures. Angirasa's son Brihaspati was a fellow student of his. Appalled by the favoritism shown by Angirasa towards his son, Shukra left his guru and became the disciple of the sage Gautama instead.
