He bargains for the king (Soma); and because he bargains for the king, therefore any and everything is vendible here. He says, 'Soma-seller, is thy king Soma for sale?'--'He is for sale,' says the Soma-seller.--'I will buy him of thee!'--'Buy him!' says the Soma-seller.--'I will buy him of thee for one-sixteenth (of the cow).'--'King Soma, surely, is worth more than that!' says the Soma-seller.--'Yea, King Soma is worth more than that; but great, surely, is the greatness of the cow,' says the Adhvaryu.
