Who The Adityas is
The Adityas are the sons of Aditi. The Rigveda gives them six whole hymns and names them in many more, and it never quite decides how many they are. One verse lists six: Mitra, Aryaman, Bhaga, Varuna, Daksha and Amsha. A late verse says there are seven. Another says Aditi bore eight.
The poets call them kings. They are bright and pure like running water. They have many eyes, and they do not sleep or even blink. Nothing is far from them. They look inside people and see the good and the evil there, and they cannot be fooled. They collect what is owed.
People do not fear them for this. One poet asks them to spread their shelter as birds spread their wings over their young. With the Adityas behind him, he says, a man is like a fighter in a coat of mail. He asks them to look down as a guide looks from the river bank, and to lead him to an easy ford. He even hands them his bad dreams and asks that these be carried far away, to Trita Aptya.
Varuna and Mitra are the great ones of the family and have pages of their own. The lesser brothers are known mostly by their names. Aryaman means "comrade". He is named about a hundred times, nearly always beside Mitra and Varuna. In the wedding hymn he and Bhaga lead the groom's friends along a straight and thornless path, and they give the bride to her husband.
Bhaga means "the giver" and also "the share". He has one hymn, a morning prayer. Rich and poor alike call on him at dawn, and the poet says that even the king himself asks, "Give me my share."
Amsha means "portion" and is hardly more than a name. Daksha means "skill". In the old list he is a son of Aditi, and one hymn says, without explaining, that he is her father as well.
As birds spread their wings over their young, spread your shelter over us, Adityas.
