on what the Buddha taught
Māna is often translated as conceit.
In the sermons we can find there are ten yokes. The first three are cut with stream-entry (the next two weakened by once-returning), the first five with no-returning, and the remaining five on virtuousness. Māna is one of those last yokes, so as long as we are not enlightened we have māna.
Conceit is excessive pride in oneself. But when we see someone acting selflessly would we then say this person is acting out of conceit? That feels a bit weird right? So how can we let this make sense?
'I was', 'I saw', 'I did', 'I want', 'I said', 'I feel', 'I think', ... if someone would use these in several sentences within a short period of time, we could think that this person is really full of him/her self. We could say that he/she is 'making it about him/her self' hence conceit. But suppose someone was asked a lot of questions like 'Where were you?', 'What did you see?', 'What did you do?', then answering them with 'I was', 'I saw', etc. wouldn't automatically mean this person must be full of him/her self. So, conceit is more about 'making it about you while it is not about you'.
At stream-entry, once-returning and no-returning not-self is understood yet a sense of self is left (SN22.89). And this sense of self is regarding things which are not-self (pañc'upādānakkhandhā), so this too is 'making it about self while it is not about self'. In this way it got the characteristics of conceit, hence conceit. Conceit, arrogance, pride, etc., are manifestations of this principle of conceit.
Having that said, the dictionary also shows that māna can also mean honor, respect, and there is a third meaning in the form of measure. An english word which would cover all three meanings is esteem. The most subtle form is the esteem 'I am' (asmimāna). And this self-esteem too is a form of measurement. Not only does esteem seem to fit better, it also steers a bit away from selfishness or ego to which māna might perhaps be reduced to. And it might be that esteem can more easily be associated with holding ('held in high esteem') and what can be held can be let go of.
Māna esteem.
