Alan Watts discusses the word tathata, which is translated from the
Sanskrit as suchness or thusness. The term is used in Mahayana Buddhism
to suggest how things look to a Buddha, to one who has experienced
enlightenment or liberation and is, therefore, called a Tathagata--one
who comes (and goes) thus. Watts shares the sense of this nonsense in
Buddhist philosophy, and its practical demonstration in Zen.
