7.15.1 "Life, verily, is more than hope. Just as, verily, the spokes are fastened in the hub, so on this vital breath everything is fastened. Life goes on with the vital breath. The vital breath gives life; it gives life to a living creature. One's father is vital breath; one's mother, vital breath; one's brother, vital breath; one's sister, vital breath; one's teacher, vital breath; a learned man, vital breath.

7.15.2 If one answers harshly, as it were, a father or mother, or brother, or sister, or teacher, or a learned man, people say to him: 'Shame on you! Verily, you are a slayer of your father! Verily, you are a slayer of your mother! Verily, you are a slayer of your brother! Verily, you are a slayer of your sister! Verily, you are a slayer of your teacher! Verily, you are a slayer of a learned man!'

7.15.3 But if, when the vital breath has departed from them, one should even shove them with a poker and burn up every bit of them, people would not say to him: 'You are a slayer of your father,' nor 'You are a slayer of your mother,' nor 'You are a slayer of your brother,' nor 'You are a slayer of your sister,' nor 'You are a slayer of your teacher,' nor 'You are a slayer of a learned man.'

7.15.4 For indeed, vital breath is all these things. Verily, he who sees this, thinks this, understands this, becomes a superior speaker. Even if people should say to him, 'You are a superior speaker,' he should say, 'I am a superior speaker.' He should not deny it."
