It has no beginning and no end, it simply is. And that's OK.

Rainer Maria Rilke: “For one human being to love another is the most difficult task of all. It’s the work for which all other work is mere preparation.”
Teilhard de Chardin: “Someday after we have mastered the winds, the waves, and gravity, we will harness for God the energies of love; and then for a second time in the history of the world, human beings will have discovered fire.”
Leo Tolstoy: “Love is life. All, everything that I understand, I understand only because I love. Everything is, everything exists, only because I love.”
Blaise Pascal: “If you do not love too much, you do not love enough.”
Emily Dickinson: “Until you have loved, you cannot become yourself.”
