TIIEORY OF ATOM is called a 'paramanu'” In. Panchastikaya-sara, some other characteristics of paramanu are also eniimerated "The substance, which has a single taste a single colour, one smell, and two kinds of sparsh (Eutaneous or touch sensation), which is the cause of sound, but is not sound itself, which is different from skandhas (aggregates of elementary particles) though constituting them, is the 'paramanu'."
The four sense-data-touch, taste, odour and colour of the four senses viz touch sense etc , respectively, are present in minutest quantities in a 'paramanu'. Only the subject of the sense of hear. ing viz sound, is not associated with 'paramanu' because sound is an attribute of skandhas" only. 'Paramanus' can only be called as one of the causes of the sound Although colour, odour etc. of a single 'paramanu' cannot be perceived by their respective senses, they are always there as its principle characteristics.
