But there is another story from Aitereya Brahmana which I have read in the Chandamama books in my childhood.In it the Brahmin Rishis insult and keep away from a fire ritual another sage born of union between a Brahmin sage and a non-Brahmin mother.In his childhood his own father does not bestow knowledge of the Vedic rituals to him as he is not of pure Brahmin descent.The Saraswati river then splits on her own and washes the feet of that mixed breed sage to prove his piousness.Needless to say that if this fiction of river splitting and washing the feet of the mixed breed rishi or sage is filtered out,one can extract facts of history which is that Brahmins did indeed marry non-Brahmin ladies once upon a time discarding the much adhered to concept of avoiding Varna Sankaram or mixing of castes/classes.

In the version of the story that I have read,when the mixed breed boy laments before his mother at the fact that his father is averse to teaching him the holy rites of religion ,she confesses to him that she is from the hard-working or hard toiling peasant caste while his father was a Brahmin and that could be the reason why he does not teach him religion.She then tells the boy that Mother Earth is highly knowledgeable and asks him to attain divine powers by worshipping and observing her.
The boy follows his mother's instructions and thus becomes quite pious.
Now across the internet we frequently come across a Satapatha Brahmana verse that says that gods/goddesses commune only through Brahmins.Then how is it that according to this myth from Aitereya Brahmana,the goddess Mother Earth divined through the mixed breed sage?Afterall the seed(semen) no longer belongs to the seed giver(man) and it instead belongs to the land into which it is ploughed(the woman) according to Hindu texts.Meaning that even if the father is the Brahmin,the offspring will always belong to the caste of the mother.
And afterall,in the Mahabharatha,Dhritarashtra and Pandu were known as Kshatriyas even though the were born of Niyog system of intercourse with supposedly Brahmin sage Veda Vyasa.And traditionally the offspring of Brahmins and Shudra Nair women were always considered belonging to Nair caste in Kerala.So one Brahmana text says that divination is possible only through Brahmins and another says that divinities also commune thorough people of other castes.So perhaps divination itself does not exist.
