What is Soul Love

So there is something I have been thinking about, Love the Lord with all your heart, soul and mind. Heart and mind I can get a handle on, but what does it mean to love God with your soul? I am not sure we understand how to feel with our soul, how to love with our soul, have to speak to or from or with. This has been a journey in learning and reading, and I'll continue with the journey, I'll keep posted on what I find and where God leads me.
