For this very reason the Vedic passage, 'He buys the Soma by means of a cow one year old, of a tawny colour, with reddish-brown eyes' (arunayâ, ekahâyanyâ, piñgâkshyâ), must be understood to enjoin that the purchase is to be effected by means of a cow one year old, possessing the attributes of tawny colour, &c. This point is discussed Pû. Mî. Sû. III, 1, 12.--The Pûrvapakshin there argues as follows: We admit that the word 'arunayâ' ('by means of a tawny one') denotes the quality of tawniness inclusive of the thing possessing that quality; for qualities as well as generic character exist only in so far as being modes of substances. But it is not possible to restrict tawny colour to connexion with a cow one year old, for the injunction of two different things (which would result from such restriction; and which would necessitate the sentence to be construed as----) 'He buys by means of a cow one year old, and that a red one' is not permissible [FOOTNOTE 222:1]. We must therefore break up the sentence into two, one of which is constituted by the one word 'arunayâ'--this word expressing that tawny colour extends equally to all the substances enjoined in that section (as instrumental towards the end of the sacrifice). And the use of the feminine case-termination of the word is merely meant to suggest a special instance (viz. the cow) of all the things, of whatever gender, which are enjoined in that section. Tawniness must not therefore be restricted to the cow one year old only.-- Of this pûrvapaksha the Sûtra disposes in the following words: 'There being oneness of sense, and hence connexion of substance and quality with one action, there is restriction.'--The fact that the two words 'arunayâ' and 'ekahâyanyâ'--which denote a substance, viz. a cow one year old, distinguished by the quality of possessing tawny colour--stand in co-ordination establishes that they have one sense; and is the substance, viz. the cow, and the quality, viz. tawny colour--which the word 'arunayâ' denotes as standing in the relation of distinguishing attribute and thing distinguished thereby--can thus, without any contradiction, be connected with the one action called 'the buying of the Soma', tawny colour is restricted to the cow one year old which is instrumental with regard to the purchase. If the connexion of tawniness with the action of buying were to be determined from syntactical connexion--in the same way as there is made out the connexion of the cow one year old with that action--then the injunctory sentence would indeed enjoin two matters (and this would be objectionable). But such is not the case; for the one word 'arunyâ' denotes a substance characterised by the quality of tawniness, and the co-ordination in which 'arunayâ' stands to 'ekahâyanyâ' makes us apprehend merely that the thing characterised by tawniness also is one year old, but does not make a special statement as to the connexion of that quality with the thing.
