Next follows the consideration of the observances (acts). Pragapati created the actions (active senses). When they had been created, they strove among themselves. Voice held, I shall speak; the eye held, I shall see; the ear held, I shall hear; and thus the other actions too, each according to its own act. Death, having become weariness, took them and seized them. Having seized them, death held them back (from their work). Therefore speech grows weary, the eye grows weary, the ear grows weary. But death did not seize the central breath. Then the others tried to know him, and said: 'Verily, he is the best of us, he who, whether moving or not, does not tire and does not perish. Well, let all of us assume his form.' Thereupon they all assumed his form, and therefore they are called after him 'breaths' (spirits). In whatever family there is a man who knows this, they call that family after his name. And he who strives with one who knows this, withers away and finally dies. So far with regard to the body.
In plain words: Prajapati created the senses, and they argued over who was best: speech wanted to speak, the eye to see, the ear to hear. Death came as tiredness and wore them out, but it could not touch the central breath. So the senses all took breath's form, which is why they are called 'breaths.' A family with someone who knows this is named after him.
