The truth is that there is only one terminal dignity - love. And the story of a love is not important - what is important is that one is capable of love. It is perhaps the only glimpse we are permitted of eternity.

This quote is saying that the only thing of lasting importance is love. It doesn’t matter what the love story is, but that we are able to love. Loving is important because it gives us a glimpse of eternity. Eternal love is more powerful than any other kind of beauty or grandeur in the world. Love can be our source of joy and strength even if it lasts for a short time. It brings us closer to understanding and feeling eternity in our lives.
