Love is as natural to us as breathing, yet it's so hard to love! We've been raised to see others as competitors, dangerous, wrong-headed, different, above or below us. Love demands that we be blind to the prejudices we've been taught. Love must be unconditional or it isn't love. That kind of love flies in the face of convention, and takes the persistence Albert talks about to achieve; yet what an achievement! How free, how wonderful we will feel when we can love without blinders or boundaries!
Only when we can love like that will we also be able to love ourselves.
This kind of love isn't easy at first, but practice makes perfect, and perfect love is worth the practice.
