How many birds do you see? Actually there is just one and the other one is a perfect reflection on the calm & clear water. Then, which one is real? Sometimes we confuse ourselves and could not differentiate reality from reflection of that reality we created in our mind. And if our mind is not as calm & clear as water, the reflection we created turns out to be totally different than the reality, which leads us to disappointment. Is your mind clean and clear to differentiate reality vs reflection?
