True Love

I have read few of your books and one of my favorites is The Path of Love. I always wonder about the quote that you gave at the end of the book. It says that “Love is not the way you feel and behave, but it’s the level of awareness”. Honestly, I have failed understanding the meaning of this quote since I have read it (which is about more than one year). Would you please kindly explain the meaning of it to me?
I also want to ask you that what is true love (love for your life-partner)? Can it change with time? And if it does, then is it a true love? May be I have made a wrong definition of love in my life, and that’s probably the reason I’m suffering emotionally. I will look forward to the right guidance from you Dr. Chopra.
