There's nothing infinite about the "love" they find, it is soon lost; but they never lose "hope", they just try to find another and same one. It's like the "life" they seek, which means selfishness, every fake thing that could ever please their ego; if they lose it all, that's what they're going to be looking for again. Both, actually, are not worthy of the word 'found', since one is not venturing into any new territory, it is the same old one in which no blessing is required to succeed. Once the "bio" stops, the eternal failure starts.
