The small lake had a pair of loons with one chick. I was surprised that the downy chick was so young this late in the season. It still had not learned how to dive.
It often swam with its head underwater--to see what food might be down there or perhaps to see where Mother Loon was or what she was bringing home to eat.
One of the big challenges in meditation is to stay alert even when we feel our energy is sinking. If we can stay as alert as the loon chick, even when we feel underwater, it is quite an accomplishment. Interest re-ignites energy, and then we are swimming along in meditation again.
