The energy you put out is the energy you get back.

對不可見事物的恐懼是每個人內心稱之為宗教的自然種子。

注釋：避免嫌疑和被人猜疑，這樣才能不犯錯誤。廣泛學習并懇切求教，才能增長知識。行為高尚而言辭謙遜，這樣才能修養身心。

And I hope you will come back here to Harvard 30 years from now and reflect on what you have done with your talent and your energy. I hope you will judge yourselves not on your professional accomplishments alone, but also on how well you have addressed the world's deepest inequities…on how well you treated people a world away who have nothing in common with you but their humanity.

In the dance of particles and forces, we find the rhythm of the cosmos.
