Bob, your poem about the wonders of the heart is beautiful and wise.  I am currently reading a book about anxiety which draws on scientific research indicating that the heart has far more to do with anxiety and stress than may have been realized.  Whereas traditional therapy to this point has focused on cognitive centers, newer research indicates that the heart center is where it's at when we want to identify, neutralize and transform negative emotions which underlie stress.  As I am reading about a breathing technique in which a therapist has his client breathe into the heart with an authentic intention to relax, and breathe out through the feet, with an authentic intention to feel grounded - I realize, yoga is everywhere.  These scientists have discovered the wonders of the chakras and energy body.  "The physical and spiritual wonder" of the heart is awesome.

Several days after writing my blog above, I was astounded to happen upon this verse in the Yoga Sutra:

"Focusing with perfect discipline on the heart, one understands the nature of consciousness" (3:35)

It's like we're jumping across the span of 2500 years to share our experiences with Patanjali.
