Think of Ni as already in existence sheet music, Fe is the conductor, trying to conduct all the 'music' coming from people (in other words, their emotions ) and trying to make sure that the music is brought together in an ongoing harmonic concerto, via Ti, which sees the purpose and builds the music towards the purpose.
Purpose is emotional harmony.
Fe conducts the orchestra, (other people) by a bit of validation here, and bit of empathy there, maybe a bit of support somewhere else.. all overseen by Ni, which is the orignal sheet music, the original 'plan'.
Tilty Red, maybe some people resent Fe because they wanna play their own freestyle music within the orchestra, and be dischordant,.. and Fe is trying to get everyone to harmonise. (Think of Lisa Simpson being thrown out of the orchestra in the opening credits of the Simpsons for playing her sax freestyle.)
