"Particles, prepositions, and roots--these three are all held to be of manifold meaning; instances found in reading are their evidence." Therefore some authors expressly give _yuj_ in this sense, and insert in their lists "_yuj_ in the sense of _samádhi_." Nor does this contradict Yájñavalkya's declaration, as the word _yoga_, used by him, may bear this meaning; and he has himself said-- "_Samádhi_ is the state of identity of the individual and supreme souls; this abiding absolutely in Brahman is the _samádhi_ of the individual soul." It has been also said by the venerable Vyása [in his Commentary on the Yoga-sútras, i. 1], "_Yoga is samádhi_." An objection however, may be here raised that "the term _samádhi_ is used by Patañjali [in ii. 29] in the sense of one of the eight ancillary parts[384] of the eightfold concentration (or _yoga_); and the whole cannot be thus itself a part as well as a whole, since the principal and the ancillary must be completely different from each other, as all their attendant circumstances must be different, just as we see in the _darśapúrṇamása_ sacrifices and their ancillary rites the _prayájas_, and therefore _samádhi_ cannot be the meaning of _yoga_." We however reply that this objection is incorrect; for although the term _samádhi_ is used for etymological reasons[385] to express the ancillary part which is really defined [in iii. 3] as "the contemplation which assumes the form of the object, and is apparently devoid of any nature of its own;" still the further use of this term to describe the principal state is justified by the author's wish to declare the ultimate oneness of the two states [as the inferior ultimately merges into the superior]. Nor can you hold that etymology alone can decide where a word can be used; because if so, as the word _go_, "a bull," is derived by all grammarians from the root _gam_, "to go," we ought never to use the phrase "a standing bull" [as the two words would be contradictory], and the man Devadatta, when going, would properly be called _go_, "a bull;" and, moreover, the Sútra, i. 2, distinctly gives us a definite justification for employing the word in this sense when it declares that "concentration (_yoga_) is the suppression of the modifications of the thinking principle." [The second or principal sense of _samádhi_ will therefore be quite distinct from the first or inferior.]
