“Ahavas Yisrael is much more powerful than Ahavas Chinam”
mobico, when the Bais Hamikdosh was destroyed, the Gemara tells us it was due to Sinas Chinam.
In other words, not only did they hate Jews (Sinas Yisroel), but it was for no reason whatsoever (he didn’t steal from him, he didn’t hurt him, just pure senseless hate).
The way to be מכפר for this and bring the Geula is through the opposite:
Not only to love Jews (Ahavas Yisroel) because he did something nice for you, or because he is a mentsch, or a perfect shomer Torah u’mitzvos (or wears the same type of hat as you), rather Ahavas Chinam – for no reason, just because he is a Jew.
