Why do we fall in Love?

"Love is the beauty of the soul." --St. Augustine
"Love is a temporary madness. It erupts like an earthquake and then subsides. And when it subsides you have to make a decision. You have to work out whether your roots have become so entwined together that it is inconceivable that you should ever part. Because this is what love is. Love is not breathlessness, it is not excitement, it is not the promulgation of promises of eternal passion. That is just being "in love" which any of us can convince ourselves we are.
Love itself is what is left over when being in love has burned away, and this is both an art and a fortunate accident.
To find the roots that grew towards each other underground, and when all the pretty blossom had fallen from our branches,to have found that we were one tree and not two."

Why people fall in love?
It is a mystery why we fall in love. It is a mystery how it happens. It is a mystery when it comes. It is a mystery why some love grows and it is a mystery why some love fails.
Sometimes, hopefully at least once in your life - the gift of love will come to you in full flower. Take hold of it and celebrate it in all inexpressible beauty. This is the dream we all share. More often, it will come and take hold of you, celebrate you for a brief moment, then move on.
If you find yourself someone in love with you but you don't love him back, feel honored that love came and called at your door, but gently refuse the gift you cannot return. Do not take advantage; do not cause pain. How you deal with love is how you deal with yourself. All our hearts feel the same pains and joys, even if our lives and ways are different.
If you fall in love with another, and he falls in love with you, and then love chooses to leave, do not try to reclaim it nor to
assess blame. Let it go. There is a reason and there is a meaning. You will know in time.
Remember that you don't choose love. Love chooses you. All you can really do is accept it for all its mystery when it
comes into your life. Feel the way it fills you to overflowing, then reach out and give it away. Give it back to the person
who brought it alive in you. Give it to others who deem it poor in spirit. Give it to the world around you in any way you can.
Love has its time, its own season, its own reason for coming and going. You cannot bribe it or coerce it, or reason it into staying. You can only embrace it when it arrives and give it away when it comes to you. But if it chooses to leave from your heart or from the heart of your lover, there is nothing you can do and there is nothing you should do. Love always has been and
always will be a mystery.
