I would suggest that a spiritual love is actually not personal, which doesn't mean it cannot exist in a situation that is very personal from an individual subjective perspective, but we might say it is bigger than that.
There's love that comes out of an idea - such as the golden rule, which is something that makes sense to a person and they may try to apply that. On the other hand there may be a deep realization of this idea so that it isn't just something the person thinks and tries to do, but rather who and what s/he is.
We tend to look to great ones in the spiritual arena as we do in others, but does this really apply when it comes to love? If nothing else even the greatest scientific and artistic minds may very well be undiscovered, but when it comes to love it's not even a question of ability. Isn't it quite possible ones that embodies love in such a way may very well be a simple person that doesn't command a lot of power or attention in the world? Yes, love is it's own power in a way, but the question is can we recognize that when it is expressed through one who otherwise possesses limited means?
Frankly it's not about what any individual person can do, it's just not about any individual person. It's a different paradigm. We might look at examples such as the widow who gave the few coins that she had as a heroic example, but there is much more going on. Ultimately love isn't about a shining example, something a great individual does - it's how people are touched. I think it was the Advaita teacher Nisargadatta that said "love is the meaning and purpose of duality." It's a coming together. Example are just examples, as great as some of them might be - but it would be missing the point if you just try to emulate the form it takes. In fact, love will call for different expressions depending on the circumstances, the particular form it takes is not important. That's why my friend describes it as love coming back for itself. It's not even a matter of this person liking another person because of their personality clicks, it's a matter of the love that is in both/all of them waking up to itself, in here and there. So I say be yourself, let that love be you. You don't have to be better at anything, have any special knowledge or ability. When it's all an expression of love, none of that matters.
Edited to add: So I am implying that such a love would be non-local, not something that starts from a certain point (loving person) and goes out in a particular direction to an other.
