His superhuman ability to see thousands of universes made Anuruddha so proud so he came and spoke to Sariputta: "I can see thousand universes as easily as one can see a fig in his own hand, however I have not been able to rid myself of mental defilements (Āsava)".
Sariputta said: " Half of what you just said is from conceit (màna). The other half is from restlessness and worries (uddhacca-kukkucca)".
That is how a saint would see matters, to that level of extreme scrutiny.
Auruddha thanked his teacher and went into deep meditation and achieved Arahant enlightenment, no longer did he have conceit or restlessness or worries.
What about us? We want too much, we want everything, and if we have a bit of something, that's enough to make us feels proud.
We look around and feel good to find other Buddhist do not go begging 8 days a month like do. That's conceit.
We look around and feel good to find other Buddhists do not listen to Dhamma as much as we do. That's conceit.
We feel good to find that nobody has as many Dhamma books as we do. That's conceit.
