In Hinduism, a Brahmarshi (Sanskrit brahmarṣi, a tatpurusha compound of brahma and ṛṣi) is a member of the highest class of Rishis ("seers" or "sages"), especially those credited with the composition of the hymns collected in the Rigveda. A Brahmarshi is a sage who has understood the meaning of Brahman or has attained the highest divine knowledge Brahmajnana.
The superlative title of Brahmarishi is not attested in the Vedas themselves and first appears in the Sanskrit epics.
According to this classification, a Brahmarishi is the ultimate expert of religion and spiritual knowledge known as 'Brahmajnana'. Below him are the Maharishis (Great Rishis).
The Saptarishis created out of Brahma's thoughts are perfect brahmarishis. They are often cited to be at par with the Devas in power and piety in the Puranas.
Bhrigu, Angiras, Atri, Vishwamitra, Kashyapa, Vasishta, and Shandilya are the seven brahmarishis. But there is another list of Saptarishi also who are also Gotra-pravartakas, i.e.,founders of Brahamanical clans, and this second list appeared somewhat later, but belongs to ancient period.
