I find that love is always found underneath our conditioning. Conditioning from the past and traumatic experiences. But also, conditioning from different social systems and institutions.
For instance, our economic system trains us to think as individual economic agents out for our own gain. This then becomes a self-fulfilling prophecy as that story creates greedy, selfish people.
"See, I told you it was true!"
But spontaneous acts of real love create a glitch in the matrix of egocentrism and survival. It reminds us that it's not real.
They're like cracks of sun shining through the clouds, saying "hey, remember this?"
It's there in spiritual texts like the Bhagavad Gita and even business books like The Thank You Economy. They attempt to unravel the stories that we have told that keep us from accessing our heart. They give us permission to do what we already know is true.
Because you cannot lose your connection to your heart, you can only be trained not to listen.
