is a feeling of bliss which is totally unconditional of the outcome.
For example, your mother, you never want to lose her at any condition though she scolded you or beaten you, you can be angry at her for sometimes.
But the moment the anger goes away, you go back to her for love.
Another example could be your passion, suppose your passion is to play guitar. You are not playing it to impress your crush, not to become a famous guy.
You are playing it, because you love that you know it. It may happen you are very bad at it and people used to make fun of this, but you still keep on doing that because of the love of your doing it, this is called love.
How to identify someone or something is love or attraction? Just ask yourself a question - am I ready to stay with it for lifetime irrespective of the pain, pleasure or any kind of outcome.
If the answer comes out from your heart is yes, then it is love and if no, then it is an attraction or even if there is any doubt between yes or no, then also it is our attraction. This is the most important point please remember.
