Some branches of Hindu philosophy propose that reality is nondual in nature. Such schools of thought—called advaita schools, from a Sanskrit word meaning “not two”—see the material world either as an aspect of ultimate reality (“Brahman”) or as a mere illusion. So how do we make sense of the appearance of variety in a metaphysics of oneness? Is there room for individual selves within advaita philosophy? What can be known? And what possible sources of knowledge are there in a nondual epistemology?
