YV 2.5g

The wings and the tail are a fathom in breadth; so much is the strength in man [1], he is commensurate in strength. He metes with a bamboo; the bamboo is connected with Agni; (verily it serves) to unite him with his birthplace. With a Yajus he yokes (the team), with a Yajus he ploughs, for discrimination. He ploughs with a (team) of six oxen; the seasons are six; verily with the seasons he ploughs him. In that (he ploughs) with (a team) of twelve oxen, (he ploughs) with the year. This (earth) was afraid of excessive burning by Agni; she saw this of two sorts, ploughed and unploughed [2], then indeed he did not burn her excessively; in that there is ploughed and unploughed, (it serves to prevent) her being excessively burned. 'He should restrain Agni when twofold', they say; in that there is ploughed and unploughed (it serves) to restrain Agni. So many are animals, bipeds and quadrupeds; if he were to let them loose to the east, he would give them over to Rudra; if to the south, he would deliver them to the Pitrs; if to the west, the Raksases would destroy them; to the north he let them loose; this is the auspicious quarter of gods and men (3); verily he lets them loose in that direction. Again he lets them loose to this quarter, the breath is yonder sun: verily he lets them loose following the breath. From left to right they turn, around their own strength they turn; therefore the right side of the body is the stronger; verily they turn with the turning of the sun. Therefore cattle depart from (us), and come back towards (us). Three by three he ploughs the furrows [4]; verily he extends the threefold (Stoma) in the beginning of the sacrifice. He scatters plants, by holy power he wins food, in the Arka the Arka is piled. With fourteen verses he scatters; the domesticated plants are seven, the wild are seven; (verily they serve) to win both sets. He scatters (seeds) of diverse kinds of food, to win diverse foods.
