Atri had already seen the entire development with his divine vision.
When Anushuya's husband Atri came back home, Anusuya called them the secret
of three children.
The mention about Atri is found in various scriptures,
with the notable being in Rig Veda.
When instructed by divine voice to do penance, Atri readily agreed and did severe penance.
One of the ancient texts of this tradition is Atri Samhita, which survives in highly inconsistent fragments of manuscripts.
Atri is one of the Saptarishi(seven great Vedic sages)
in the Hindu tradition, and the one most mentioned in its scripture Rigveda.
Atri embraced the three children and with their power,
they converted three children into one child, with three heads and six hands.
The Atri hymns of the Rigveda are significant for their melodic
structure as well as for featuring spiritual ideas in the form of riddles.
While the fifth mandala is attributed to Atri and his associates,
sage Atri is mentioned or credited with numerous other verses
of the Rigveda in other Mandalas,
Atri(Sanskrit: अत्रि) or Attri is a Vedic
sage, who is credited with composing a large number of hymns to Agni, Indra and other Vedic deities of Hinduism.
The fifth Mandala(Book 5) of Rigveda is called the Atri Mandala in his honour, and the eighty seven hymns in it are attributed to him and his descendants.
Atri's hut is described to be in Chitrakuta,
near a lake with divine music and songs, the water loaded with flowers, green water leaves, with many"cranes, fisherbirds, floating tortoises, swans, frogs and pink geese.
