Māna: Conceit
The mind forever measures where it stands against others. "More highly than he ought" is that mind on tiptoe, sliding itself a few inches above the man in the next seat. This ranking is stubborn, clinging on long after coarser faults are gone, still murmuring "I am the better one" just when you thought you had grown humble.
Sakkāya-diṭṭhi: Identity view
This takes the changing bundle of body and mind for a fixed "me." Before a man can "think of himself" too highly, he assumes there is a solid himself standing there to be weighed at all. Look closely and that himself is only shifting parts and passing moods, like weather with no owner behind it, and the whole contest over rank loses its ground.
Yathābhūta: Seeing things as they are
Here you know yourself at true size, according to what is so. "To think soberly" means setting down the wine of self-importance and reading your own measure with a clear eye, the way a steady hand reads a ruler. Drink makes a small man feel tall; sober sight lets him see the honest line where he stops, no higher and no lower.
Nivāta: Humility
This is a mind laid low and easy to teach, its winds of pride fallen still. Where conceit stands on tiptoe, humility lets a man rest flat on his own ground, with no urge to climb above "every man that is among you." Like water, it settles to the lowest place and grows calm, and from that low seat it can still receive what a proud, tilted cup would spill.
Saddhā: Faith
This is the trust and confidence each person carries to some degree. Hear "the measure of faith" as a cup filled only to a line and placed in your hands, a portion dealt rather than seized, which leaves nothing to boast of. Pride over it makes as little sense as bragging about a card you were dealt, so the tall man and the low man can set their measuring down and simply hold what was given.
