The Saptarishi (from , a Sanskrit dvigu meaning "seven sages") are the seven rishis who are extolled at many places in the Vedas and Hindu literature. The Vedic Samhitas never enumerate these rishis by name, though later Vedic texts such as the Brahmanas and Upanisads do so. They are regarded in the Vedas as the patriarchs of the Vedic religion.
The earliest list of the Seven Rishis is given by Jaiminiya Brahmana 2.218-221: Agastya, Atri, Bhardwaja, Gautam, Jamadagni, Vashista and Visvamitra followed by Brihadaranyaka Upanisad 2.2.6 with a slightly different list: Gautama and Bharadvaja, Visvamitra and Jamadagni, Vashista and Kasyapa and Atri, Brighu. The late Gopatha Brahmana 1.2.8 has Vashista, Visvamitra, Jamadagni, Gautama, Bharadvaja, Gungu, Agastya, Bhrigu and Kaśyapa.
In post-Vedic texts, different lists appear; some of these rishis were recognized as the 'mind born sons'(Sanskrit: manasa putra) of Brahma, the representation of the Supreme Being as Creator. Other representations are Mahesha or Shiva as the Destroyer and Vishnu as the Preserver. Since these seven rishis were also among the primary eight rishis, who were considered to be the ancestors of the Gotras of Brahmins, the birth of these rishis was mythicized.
In some parts of India, people believe these are seven stars of the Big Dipper named " Vashista", " Marichi", " Pulastya", " Pulaha", " Atri", " Angiras" and "Kratu". There is another star slightly visible within it, known as " Arundhati". Arundhati is the wife of Vashista. The seven Rishis in the next Manvantara will be Diptimat, Galava, Parasurama, Kripa, Drauni or Ashwatthama, Vyasa and Rishyasringa.
