We notice that meditation does not progress in a linear fashion, with one sitting better than the next. Instead we find ourselves sitting in the heart, sensing the waves of our body and mind, receiving and observing. Like anything else, this requires patience and practice.
"No one is born hating another person because of the color of his skin, or his background, or his religion. People must learn to hate, and if they can learn to hate, they can be taught to love, for love comes more naturally to the human heart than its opposite."
-Nelson Mandela (1918-2013)
