Real love is nothing but identification with the beloved. In extreme cases, an individual forgets his own identity and is fully identified with beloved.
When you are in real love you can experience the feelings associated with it in real times. It so happens in most cases that you cannot avoid yourself thinking about the person whom you are in love with. When he or she is there with you nothing else seems to catch your fascination rather than the one you love. You only see the positives of that person such is the magic of love. You might feel like living in a heaven on earth.
This are some of the feelings associated with true love I know of. There are a whole list of it and can be easily converted into a good article but since this is a post I have limited myself only to an extent.... :)
