Thank you for your question!
To say to feel with “your heart,” is to say to feel with your whole being. We are in tune with this experience usually in the “negative” side. When your girlfriend leaves you for another one; when your favorite pet passed away, etc. Have you experienced that?
What is the “location” for that suffering? 🙂
The location does not matter, what matters is that your are feeling completely, whole-heartened that pain, and there is no escape for it.
Now, emerge that feeling when you say “Baba with your heart,” out of love or when the experience of the soul appears in your life.
That experience is you, the soul expressing. That experience is what makes you alive from living a “life-less” life in the head, that is to “feel with the heart.” To be alive.
