If your mind has any limited desires, they will not allow you to become content. When you are walking in the sun, your shadow goes ahead of you and if you try to catch it, you won’t be able to. When you turn around, your shadow will follow you.
In the same way, desires attract you and make you cry. Let go of them and they will follow you. Those who ask for something can never become full and complete. To chase any limited desire is like trying to catch a mirage.
