心法

Mental dharmas, idea-- all 'things' are divided into two classes 色 and 心 physical and mental; that which has 質礙 substance and resistance is physical, that which is devoid of these is mental; or the root of all phenomena is mind 緣起諸法之根本者為心法. The exoteric and esoteric schools differ in their interpretation: the exoterics hold that mental ideas or 'things' are 無色無形 unsubstantial and invisible, the esoterics that they 有色有形 have both substance and form.
