"Life is unfair" is certainly one of the possible opinions on life and on this particular event. Another equally valid opinion could be "life is fair", and the one I prefer a simple "life is".

"Life is unfair" in this case comes from a sense of entitlement. Feeling that the particular congregation should have recognized and appreciated your contribution. Well, they did not. That is truth. Did it hurt your ego? Why should it? You just did not fit with them, and they recognized that. They wanted you to do, do, do, little busybodies them, work, work, work. Do you want to have your life and in particular your spiritual life reduced to that?

Perhaps you can see, in this instance, that "life is fair" because not being part of their assembly you may now feel encouraged to seek a different group, a group with which you will feel more at home.

And you never know, perhaps also "life is fair", because have you stayed, you might have been on a bus one day, going to some retreat or entertainment function, and maybe a tire blew up and maybe you would have ended in a hospital, injured, and at this time such a turn would not have served your growth and evolution of spirit. Why argue with your guardian angel?

"Life is" attitude, however, is the most empowering one of those three. You simply realize that that no amount of your suffering over it, will undo a smallest thing that happened, will not make a tiniest spec of dust that was tossed certain way, become un-tossed. Taking that position you do not presume to know better, you avoid becoming entangled in purposeless conflict with what happened and you are most free to go on with your life, free of obligation to stand there arguing how unfair they were, how unfair life was, e.t.c. and because you are not so entangled you are most free to take the next step that servest your highest good.
