Love is a pleasant emotion within you. Even if the other person goes away, you can still experience Love. - Sadhguru.
We feel it's dependent on outside situations. That's how our perception builds up as we grow.
To experience it as independent from outside, first we have to be free from outside situations.
As long as we experience ourselves only as persons then this possibility seems almost impossible phenomenon to happen.
As long as we are only some persons then if other person goes away we feel helpless, we feel we are unable to have that pleasant emotion without them. We feel broken inside. As if some part of us have been torn apart from us.
Whereas as be-ing, we feel fulfilled within. What are we, the other person is also the same. Coming, appearing and going all are expression of same reality. And we are that.
So, how we can be without experiencing Love. We shall always experience that.
