This concept is contrasted with what the Madhyamaka tradition regarded as the incoherent notion of svabhava because of the "ultimate truth" of this concept that follows from the dependent arising of all phenomena. A form of this concept serves as the "basho," or topos, that situates all other things in the thought of Kitaro Nishida, a thinker of the Kyoto School. Avalokitesvara equates rupa, or form, to this concept in the Heart Sutra. In Buddhist thought, this property of the self is captured by the term "anatta" or "anatman," and it is more generally captured by the Japanese "mu" and Sanskrit "sunyata." Nishida (10[1])stated that the polar opposite of this concept is the basis for Western philosophy as studied in ontology. For 10 points, the Latin term for what concept lends its name to the philosophical position of nihilism? ■END■
