Love alone could waken love

[Prince charming]

I found a sentence in textbook. That is:Love alone can waken love. Is there anyone can tell me the concrete meaning about it?

 

[MikeNewYork]

My guess is it means that a person expressing/demonstrating love for another person can cause feelings of love to develop in that other person.

My guess is it means that a person expressing/demonstrating love for another person can cause feelings of love to develop in that other person.

And also that that alone can do it.
