First you need to clarify true love,
If you mean one person on the earth for each of us, then I would respond with; that is as silly as saying, and excuse me for quoting George Carlin, there is an invisible man who lives in the clouds, who listen to everything you say, every second of every day. And this man has a list of ten things you must not do, and if you do any of these things he has a place full of fire and burning and torture and anguish and he will send you there for eternity to burn and scream and suffer.....But he loves you!
Now if you mean an immediate connection to a person that is undeniable and has an overwhelming feeling, then I would say yes. Believe it or not there is a chemistry to love and based on certain factors you are subject to a number of air-based hormones that will send extremely strong signals of joy straight to your brain. If a female, or a male as the case may be, has the appropriate mix of hormones it can send one into an erotic frenzy.
Peace
