This is clear from the meaning of 'that he could breathe again' as the fact that there was no longer anything undelightful, and so no longer any weariness. Regarding the weariness and lack of delight experienced by those who use reasonings that arise from utter falsities, see above in 7392. What is delightful causes a person to breathe freely and fully, whereas what is undelightful prevents him from breathing freely or fully. So it is that 'he could breathe again' means that what was undelightful - that is, the weariness - ceased.
