The Kingdom of God is also said to be like a treasure that someone finds and hides in a field. Then, in his joy, he sells all he has and buys that field. If you are capable of touching that treasure, you know that nothing can be compared to it. It is the source of true joy, true peace, and true happiness. Once you have touched it, you realize that all the things you have considered to be conditions for your happiness are nothing. They may even be obstacles for your own happiness, and you can get rid of them without regret. We are all looking for the conditions for our own happiness, and we know what things have made us suffer. But we have not yet seen or touched the treasure of happiness. When we touch it, even once, we know that we have the capacity of letting go of everything else.
— Thich Nhat Hanh, Living Buddha, Living Christ
