Straight to the heart, a jolt flows, making you start.  Why this connection between your heart and others’, when the heart is just a pump—a physical organ?  Because, my friend, it is not the physical heart that jumps—it is the heart of the soul, which just happens to have its greatest concentration of energy centered upon the locus of the physical heart.  Scribes and poets have known this for eons, and thus the heart-organ did become the poetic symbol for love—for, who can deny the feelings of love in the chest when one cares deeply for another?  This is not the physical organ where the feeling resides, but the heart chakra, as you do call it.  Tune in to this vibrant energy center and feel the love.  Sit in the silence and ask to be filled with love.  Focus on the heart center and experience your true nature.
