Mānasaputra

Mānasaputra is a combined Sanskrit term meaning the "mind-born" or "sons of mind" (from mānasa (मानस) "mind" + putra (पुत्र)"son"). In Hinduism they are known as the Seven Rishis or Prajapati.

The online Mythology Dictionary they are defined as follows:

Wise men, created from the brain of Brahma. They are listed as Atri, Bharadwaja, Gotama, Jamad-agni, Kashyapa, Vashishtha and Vishwamitra. Vishnu, in his sixth avatar as Parasurama, delivered the world into their hands and they now appear in the sky as the seven stars of the Plough constellation. Another list gives Agastya, Angiras, Atri, Bhrigu, Kashyapa, Vashishtha and Vishvamitra while another lists Angiras, Brighu, Daksha, Kashyapa, Narada, Vashishtha and Vishvamitra. Yet another list gives ten, omitting Vishvamitra and adding Atri, Kratu, Pulaha and Pulastya. Some accounts list fourteen: Angiras, Atri, Bharadwaja, Brighu, Daksha, Gorama, Jamad-agni, Kashyapa, Kratu, Marichi, Pulaha, Pulastra, Vashishtha and Vishvamitra. These personages are often referred to as the Prajapati. In some accounts, known as Manasa Putra, Manasaputra, Prajapati, Seven Brahma Rishis, Seven Sages, Seven Seers, Saptarshi or rishi.
