四大

mahābhūta, 四界; 四大界. The four elements of which all things are made; or the four realms; i. e. earth, water, fire, and wind (or air); they represent 堅, 濕, 煖, and 動 solid, liquid, heat, and motion; motion produces and maintains life. As 實 active or formative forces they are styled 四界 (四大界) ; as 假 passive or material objects they are 四大; but the 成實論 <Satyasiddhi śāstra> disputes the 實 and recognizes only the 假.
