I feel bad for your acting teacher. He's been hurt and now lives deep within a hurt story inside his head, probably blaming himself for what happened, though he'd deny it until his dying day.
To me, love is something which encompasses yet goes far beyond words. It's shown through our actions, sometimes just by being there, holding space, accepting something precisely as it (or s/he) is. At the same time, it's always within us, like a single, sustained note, often so quiet we can barely hear it, but it is the very essence which defines us as beings.
As we grow as individuals, we learn to let that inner love flow outwards most clearly, by removing all of the obstacles WE have set inside ourselves to it. Possessiveness, judgement and conditions all come from fear, not from that inner love, no matter how they are worded.
And St. Augustine said it very simply: "Love, and do what you will." He was speaking in a religious context, but it applies to everything, really, at its best.
But I feel love is about honoring others as much as yourself --- not above, not below, but in a way that goes beyond comparison of one to another. It's a feeling of completeness, wholeness, a feeling of coming home, even though you never truly left.
