When we love someone our love becomes demonstrable or real only through our exertion - through the fact that for that someone (or for ourself) we take an extra step or walk an extra mile. Love is not effortless. To the contrary, love is effortful.

It is not selfishness or unselfishness that distinguishes love from non-love; it is the aim of the action.

Ultimately love is everything.

Since [narcissists] deep down, feel themselves to be faultless, it is inevitable that when they are in conflict with the world they will invariably perceive the conflict as the world's fault. Since they must deny their own badness, they must perceive others as bad. They project their own evil onto the world. They never think of themselves as evil, on the other hand, they consequently see much evil in others.

As I grow through love, so grows my joy, ever more present, ever more constant.

Nirvana or lasting enlightenment or true spiritual growth can be achieved only through persistent exercise of real love.
