The teaching that all is unreal. The 法相宗 Dharmalakṣaṇa School divided Buddha's teaching into three periods:

(1) the Hīnayāna period, teaching that 法有 things are real;

(2) the 般若 (sa) prajñā period, that 法 空things are unreal;

(3) the Huayan and Lotus period of the middle or transcendental doctrine 中道教.
