The lake of clear Joy and cloudy Doubt

"I was standing at the edge of a clear lake, the water so clean that I could see every fish swimming below. I cast my line and began catching them. Some were very colorful and beautiful, shining in the light. I was so happy to catch each one, and after admiring them, I gently let them go. I also caught a few smaller fish along the way. Later I went back for more fishing, but something had changed. The water was no longer clear. It had turned cloudy, and I couldn't see the fish anymore. When I woke up, I felt a little puzzled, as if something good had slipped away. The happy feeling of the catch was still with me, but it was mixed with a faint, uneasy question about why the water had changed."
