Bhagavad Gita 10.6
महर्षयः सप्त पूर्वे चत्वारो मनवस्तथा।मद्भावा मानसा जाता येषां लोक इमाः प्रजाः॥
maharṣayaḥ sapta pūrve catvāro manavastathā |madbhāvā mānasā jātā yeṣāṃ loka imāḥ prajāḥ ||
The seven great sages, the ancient four, and the Manus, possessing powers like Mine (due to their minds being fixed on Me), were born from My mind; from them, these creatures have been born in this world.
The seven Great Seers, the progenitors of mankind, the Ancient Four, and the Lawgivers were born of My will and come forth directly from Me. The race of mankind has sprung from them. (Mareechi, Atri, Angira, Pulah, Kratu, Pulastya, Vahishta; the Masters: Sanak, Sanandan, Sanatan, Sanatkumar.)
