In October 2012, I attended a lecture given by the Dalai Lama in a cavernous auditorium at the Massachusetts Institute of Technology. Even without words, the moment would have been profound: one of the world’s spiritual leaders sitting cross-legged in a modern temple of science. Among other things, the Dalai Lama spoke about sunyata, translated as “emptiness,” a central concept in Tibetan Buddhism. According to this doctrine, objects in the physical universe are empty of inherent and independent existence — all meaning attached to them originates in constructions and thoughts in our minds. As a scientist, I firmly believe that atoms and molecules are real (even if mostly empty space) and exist independently of our minds. On the other hand, I have witnessed firsthand how distressed I become when I experience anger or jealousy or insult, all emotional states manufactured by my own mind. The mind is certainly its own cosmos. As Milton wrote in “Paradise Lost,’’ “It [the mind] can make a heaven of hell or a hell of heaven.” In our constant search for meaning in this baffling and temporary existence, trapped as we are within our three pounds of neurons, it is sometimes hard to tell what is real. We often invent what isn’t there. Or ignore what is. We try to impose order, both in our minds and in our conceptions of external reality. We try to connect. We try to find truth.
