If I may ask, what is the 'master' point of view? Is that under a title?
Isn't working on a relationship what makes it work?

I'll comment on both things:
The regular approach to relationship, and life, is that if something is not to our liking we need to do something to fix it. The Master knows that all is well and, like you said, they can make a choice and change from within. By expanding their consciousness the Master allows their energies to serve them. And there comes a point when life flows smoothly, effortlessly. In the example you mentioned, the supprt of a not-well spouse is not for the sake of "working on the relationship" or because that's what a loving spouse should do, but rather because that supporting behavior is an act of expression of the master. As such, it flows effortlessly and benefits the spouse. All in all, my posts are all about the master approach to life. In this comment i touched it very briefly. :)
